Too much on my mind,can't sleep!!!!!!!!

I am 34 weeks pregnant and I can't sleep because I have too much on my mind. I just want to be ready and have a plan for when I go into labor. I already told my mom that I want her to watch my 2 kids when it's time for me to go to the hospital. She lives about 15 to 20 minutes away from me. If she happens to be at work at the time, I can always just call her and she will come. I haven't told my husband because I know he will say  "well why can't my mom watch the kids since she is just blocks away?" I have a feeling he will get mad. I honestly feel like my mom is the next best thing since me or my husband will not be able to. When I had my son 2 yrs ago,I left my daughter with my Mil and I missed her the entire time I was there. My Mil brought my daughter to visit me and my daughter looked like a bum with messy hair. When it was time for them to leave, I cried. My Mil is always watching other people's kids, like her other grandchildren or kids that she babysits for. I feel like my kids won't be cared for the way that they should since she already has her hands full. So this time I want my kids with my mom. I know I won't be stressing out about what they are doing while I'm away. Am I wrong for feeling this way?
