Congratulations! Good for you to ask for help/suggestions/advice now, especially here on Mamasource.
Ok...where do I start....
Read, read, read...go to the library and check out books. You and your child are unique and how you handle situations is up to you. There are so many different options out there for moms about how to raise a child and what works with me may not work for you. As far as sleep goes...the book I would HIGHLY recommend buying or checking out is The No Cry Sleep Solution by Elizabeth Pantley. Awesome book and gives such wonderful advice and suggestions. Read it now and as he gets a little older, you can start more of a routine with him.
Ok, here is what I would suggest if it were just me and you and we were old friends!
ROUTINE, consistency. Now, that doesn't mean everyday at 2 you do this, or at 12 you feed lunch, and if you forget or are late, it's the end of the world, no. Keep your daily routines simple and similar. Watch him for his cues, at this point he will probably be nursing (or formula fed) every couple of hours, or even every hour. (Cluster feeding - perfectly normal!) I co-slept with both of my kids, my daughter longer than my son, only b/c he didn't like to snuggle and be cuddled, he slept much better on his own. Start out with having a bassinet in your bedroom at night. If you have a two story house, I'd suggest if you can, a bassinet or pack n' play upstairs and downstairs. If he's your only child, you can keep him with you in all rooms or at least close by. Saves the trips up and down the stairs.
Wear him, yes, put him in the sling, being close to you provides security and helps him fall asleep and stay asleep. There are sooo many different versions of slings on the market, you'll have to decide on which one you like and works for you. We have and like the Dr. Sears baby sling. Sleeping at this point probably, depending on him and his personality, won't be consistent until at least 4-5 months, (maybe!) Starting at about 8-10 weeks start a good nighttime routine, do the same thing every night. Modify it on nights when you know he's tired and you don't have as long, or things aren't going as timely as you like. Vice versa if you have longer. Take a warm bath at night, lotion, baby massage, read books, cuddle, rock etc...the idea and it WILL eventually happen is to be able to get him to go to sleep on his own with out you (or bottle). In the beginning, my little guy and girl would fall asleep at the breast during our last feeding before bed. This normal and ok to do, but as he gradually gets a little older, try feeding him and removing him from the breast/bottle before he falls asleep, this way he doesn't associate the milk in order to go to sleep. You want to put him down drowsy or even wide awake and get him to fall asleep on his own. This will not be easy, as since this is your first child, it will probably test your nerves, especially when you hear him crying. It only gets better when they learn how to stand up and call you name! (my daughter was terrible at standing up and crying/calling Mama, at the top of her lungs! Tears at your heart strings!) But remember this WILL eventually happen!
Anyway, If you like the idea of co-sleeping, go for it, don't let others tell you differently. My folks (the lovely grandparents that they are), didn't like the idea of this, and had their opinions and highly vocalized them to me, don't let this bother you. Do your research and make sure you are doing things right, and everything is safe for you two. Sleeping in a bassinet or even a crib at this point is good to. You decide when to move them out of the bassinet into their crib. Every child is different, my son grew to fast, he moved into his crib much earlier than my daughter, but everyone is different.
Don't believe what others will say about feeding kids food/cereal at this age. It is highly recommended by the AAP (American Academy of Pediatrics) that you wait until the age of 6 months before feeding them solids. You can feed as early as 4 months, but you increase the risk of food allergies and other problems. There is no proof that you need to feed them anything other than you (or formula) until then. Enjoy the bonding you have with him now and wait before you have to increase your grocery bill to start buying or making baby food! It ain't cheap! Which brings me to my next point....make his own food, this will depend on you, your personality, do you have the time, but what is so neat and amazing, is the amount of money you will save when you make your own food! It is soooo easy and you know exactly what you are giving him. Check out: www.wholesomebabyfood.com for awesome ideas, advice, and recipes to help you get started on this. LOVE IT!!
DON'T put anything in a bottle except milk/formula!!!! I hate reading other people's advice about putting cereal in the bottle!! It is unsafe, and does NOT help your child fall asleep or stay asleep. Chances are when you start feeding him solids, you will notice a few things...he'll probably start sleeping in longer stretches at night, and your milk supply, if you are breast feeding, will decrease, b/c you are introducing, not substituting, food into his diet.
Ok....I think I've covered it...I hope. If you have ANY questions, please feel free to email me through Mamasource and I will gladly help you in anyway possible. I feel very strongly about my thoughts about sleeping and eating and breast milk vs formula so I may come across as a little forward, but I've only learned from my experiences!!
Good luck!
