I dont have any of the first with my baby

Raynee

My boyfriend takes my 9 month old to his fathers everyday . I just found out that fed him scrambled eggs. They were the ones to do all the first with him. I'm his mom but u dont feel like it at all. I got yelled at last week because the baby lost a half of a pound. Than I found out it's just because he is being more active. What am I suppose to do.
