Grandma got switched to nights for work and that's what I work so now baby girl has to stay with a family friend...I'm kind of worried and nervous...too many people lately are snakes dressed as lambs. I don't want my baby girl to get hurt while under their care like so many other babies lately :( Not to mention my girl is very attached to mommy and grandma and not so fond of others so she'll cry and be heartbroken T.T Any suggestions on how to make it easier for her? She'll be there from 3:30-9 some nights and until 11 other nights.
