I am a working mom and I nursed all four of my babies. The first thing you need to do is have a heart to heart talk with your husband. He is going to have to start doing more around the house while you are nursing the baby. Even if he is already helping a lot he will need to do more for the next year while the baby is nursing.
You need to focus your energies on nursing a baby and working. First, you need to set your alarm for 30 minutes early every morning and nurse the baby a long time first thing in the morning either before or after you shower and get ready. That will jump start your milk production every morning.
Now look at your work day and figure out when you can pump. If you work 4 hours you can probably only pump one time. If you work 8 hours you can pump two short times in the morning and in the afternoon and one long time at lunch. Talk to your employer and work this out. The hospital pump will work well. Use the double pumping one so that you can pump both sides at the same time--it is twice as quick. It always helped me to find the quietest place out of all the noisy places at work and pump. I put a photo of the baby in with the pump. I seemed to get more milk when I looked at the baby and thought about the baby and not work while I was pumping.
You need to drink more fluids at work. Buy a big container and put ice and water in it and keep it with you all day long or buy a case of bottled water and keep it at work. Make sure you are drinking the equivalent of one bottle of water at least 30 minutes before you pump every time.
When my milk supply got low I would go into work about 15 min before everyone and pump first thing in the morning to build my milk supply. I also did that when I knew I was going to have a crazy busy day at work and I didn't know if I would find the time to pump that day. Before you leave the office drink a big glass of water or juice so that you have plenty of milk when you get home.
When you get home lay down and nurse the baby before you do anything. Dinner can wait or you can teach your husband how to start dinner and you can finish it after you nurse the baby. Take that 20 or 30 minutes and relax and nurse your little one. It is a nice transition from work to mommy time.
When you put the baby to bed at night nurse the baby for a long time and make sure the baby is really full when you put the baby to bed. Then wait 30 minutes and pump. That will give you extra breast milk to freeze and use if your milk supply gets low. At first you will not have much milk because the baby has not been nursing at that time. But after about a week you will have an extra feeding for the day. If the baby wakes up before the 30 minutes then nurse the baby back to sleep and give up for that night. But, if the baby stays asleep get that extra feeding of milk and freeze it.
Fluids are critical to having enough milk to feed your baby. Keep a bottle of water or glass of water with you at all times. If you notice that your milk supply is low switch to juice. I always produced more milk when I drank something with nutrients in it, like juice. Do not drink anything with caffeine in it. Caffeine dehydrates you and it will decrease your milk supply. No coffee, no tea, no cokes, nothing with caffeine. Keep track of how much you are drinking and make sure you are getting a minimum of 8-10 glasses of fluids a day. Think of it like this--every time you nurse you need to drink something and then you will have enough milk for the baby.
Eating a healthy diet is critical to having enough milk for the baby. Cut out anything that is junk food or sweets in your diet. Eat a healthy diet and you will increase your milk supply.
Rest is critical to having enough milk to feed your baby. Go to bed at least an hour earlier than normal every night because you are going to be getting up earlier in the morning to nurse the baby. Leave the dishes in the sink. Leave the living room that needs to be picked up. Put one load of clothes in the washer and ask your hubby to put it in the dryer before he comes to bed. If one hour earlier is not enough then go to bed earlier than that. Set a bedtime and stick to it. Ask your hubby to do the things that you didn't get done.
On your days off sleep in, take a nap during the day, go to bed early and rest rest rest. The more sleep you get the more milk you will produce.
Now let's talk about stress. Stress can decrease your milk supply. Try to relax and enjoy your baby. It doesn't matter if your house is spotless. It doesn't matter if all the laundry is done. There is a lot of stress being a working mom--stress from work, stress from trying to get everything done at home, stress from trying to be super mom to your new baby. Just relax and do what you can and don't worry and fret over everything else.
Nursing your baby is your first priority for the first year of your baby's life. Have a heart to heart talk with your husband and get him on board with this. Nursing gives your baby nutrients and immunities to illness that the baby will not get with formula. In the grand scheme of things it is only one year of your hubby helping out more and it is so worth it because it gives your baby a healthy start and it teaches your husband how to help more around the house and that will make your marriage stronger.
My husband seemed to get it when I described it as a "team." We are a team and we have X,Y, and Z to get done with nursing the baby and taking care of the baby being the first priority of our team. The other thing we did was split up the baby responsibilities so that he didn't end up with just the lousy housekeeping responsibilities. For example, I would pick up the kitchen and he would give the baby a bath. I would nurse the baby and he would wash the pots and pans. I would put a load of laundry in the washer and he would dry it and fold it. When we divided everything up it seemed to work the best.
My suggestion would be to drink fluids, get plenty of rest, try not to stress out about it all, and get your hubby on board and helping more. If nursing does not work out switch to formula. You are not a bad mom if you can't do it all and need to bottle feed. Good luck with your new baby!
