babysitting help.

Stephanie • I'm married and blessed with a two rainbow boys! A baby on the way & 3 babies in heaven.
Hey ladies, I just started babysitting and the little girl I'm watching is super clingy.
I love that she is clingy because my son is so independent. Nice change. The only issues I'm having is during nap time. She will only sleep in my arms. The mother says she holds the baby to sleep then lays here down.. well as soon as I get up and move to lay her down she wakes up screaming.i can't hold her the whole time while she sleeps because I'm pregnant and get uncomfortable really fast. Any tips on how I can get her to adjust at my house?
