My boyfriend and I are getting a place together soon. He has a 4 year old (possibly) autistic daughter. I'm so scared she is going to end up majorly hurting our 1 year old since all the toys won't be confined to one bedroom anymore and I plan on having my daughter's toys in the living room. She has been caught pushing and kicking her many times before and will start screaming if my daughter tries to play with her and will yank the toy away. He works all the time so I will be the one keeping his daughter while he works (he gets her weekends, every other holiday, and the entire summer). I'm just so scared and anxious.
