My husbands mom and sister have kept my 4 month old overnight once before. They want to again. am I a bad mom for letting her spend the night away from me so young? She is bottle fed, and she did a really good job the first time. I cried a lot, but I am so exhausted I can barely see straight. I have no help at home from my husband. He was raised in a family where the men do not help with babies at all.. It is really stressful for me and I feel bad for needing a break. I love my baby so much, but it is really taking its toll on me.
