I recently took in a 13 month old daycare child that is here once a week. The parents seems to be practising their version of attachment parenting. Which makes things a bit difficult when transitioning. But I am fine with the crying. However, she throws up on demand. Before 8am this I had already cleaned up three things of throw up. It is taking away from the other children, and is not sanitary. I am not sure what to do. The parents know that she vomits on demand when she is not being paid attention to or is upset. I cant get her to have a nap, so she is exhausted on top of everything. I have a few things, but do you all have any suggestions?
