Welcome back Raisa. How old is the little one? I was just babysitting my 2 month-old nephew a few days ago and all was going well until he started crying. His diaper was fine. I tried feeding him and he wasn't hungry. Every time I put him down he cried. Every time I sat down with him he cried. So I walked and patted him for 30 minutes until he was sleeping soundly and looking quite adorable. I already knew from my last nephew how everything was, but just thinking about dealing with that everyday is exhausting. I hope you are coping well with it.
It's got to be tough for him since there are no bears or sharks around here...
