M.S.
Hi! I became a stay-at-home mom about 2 years ago. It's tough some days, but I think in the end it is worth the time and memories with the kids. They grow up so fast!
As far as a routine goes, I really don't have one except for the one my 7 month old is on. My husband works in the mortgage business and he is gone everyday from 8am until 8 or 9 pm. So, I feel you on the issue of wanting to spend quality time with him. My husband will come home and just want to unwind by watching TV. It's hard to get him to pay attention to me sometimes, but I know that he is working so hard so that I don't have to. So I let him have his space. We try to go places or just do something together around the house on the weekends, since the weekdays really don't leave us with much family time at all.
I don't know how old your children are, but I have my daughter help with all of the housework and yardwork so that on the weekends, nobody has to do anything. It wasn't always this way, but I found that if it meant I could get my husband to spend time with us, I was willing to do it.
Anyway, that's my story. Don't feel alone in this department! But as for routines, you could try to schedule things that you need to get done throughout the week, I use a daily planner. That way, what I don't get done one day, I move to the next day. Life is too short to stress about what gets done and what doesn't. The main thing is to enjoy life and your kids. Just remember to schedule play time everyday!
One more thing, have lunch with friends regularly. That helps me to stay in touch with my friends who work outisde the home!
