I feel like a peice of shit mom.. my 4 1/2 month old cried for 20 minutes in my arms before bed. He had his bath, ate his bottle and played. Rocking him and walking didn't do anything to help. He's asleep now after an extra bottle and some meds for teething.. I'm on my couch waiting for the laundry to finish spinning with ice cream and wine.
We've all been there. Promise. The hospital I was at even makes all discharging moms watch a video about what to do when baby won't stop crying and it says that sometimes baby will cry for no reason at all.
You're not a bad mom at all!! I'm not a mom, but I've been babysitting my niece since she was 6 months old, I've been there when my sister feels the same way, it's not you at all, you're doing everything you can!
I've been there. You are not a shit mom, you made sure your baby had everything they needed. At that point I don't think there is anything else you can do.
