need advice from other Mommys

Nicole
This here is my princess Carley I recently started working as a nanny to two other kids the kids I nanny are 3 and 1 my princess is 1 I get to take her with me to work. She's use to my 100% attention but when she's at the house I work at she does nothing but cry and that takes my attention away from the other two kids. Does anyone have any advice for this mama that is going to lose her mind
