Maternity leave is coming to an end :( in Life as a Mom of 2 boys.....and a girl!!

I have to go back to work in 54 days and I'm starting to panic. We can't afford daycare and I prefer to raise my kids myself so I have to work nights and watch the kids all day by myself. I will get 3-4 hrs of sleep before they get up in the morning and then hopefully a couple hours when they nap together in the afternoon. I'm tired just thinking about it. I honestly don't know how I'm going to do it. I managed it when it was just Cody but two kids is totally different, especially since Miles is a fairly difficult child right now. I wish there was someone who could help me out like a family member but there isn't. I might end up so tired that I spend every last extra cent I have on some kind of daycare for the kids. If I can't handle it I will have no choice. I am just really stressed because I'm not sure how I'm going to manage this. Mike gets home at 5 each day except for Fridays where he is home at 11:30 (soooo having a long nap that day!) I can't have a nap when he gets home because I need to make dinner then and spend time with him. Maybe I could put them in daycare for 2 half days and suck it up for one day and the other day would be the Friday when Mike is home early? I think that would be like $80 a week. I just don't know...
