<human>: Keeping things short, after a week with his Dad and myself, I was dropping my stepson off at daycare.  I told him that Mommy would be picking him up and asked if he was excited to see her (since he hadn't seen her all week).  He said no.

I asked why and he told me "I get sick because of my feelings".  When I asked what feelings he was talking about he said "they hit me" and he got very embarrassed and didn't want to talk about it anymore (wouldn't answer any questions).  Of course I didn't interrogate him or anything, just asked "who?" and told him he was safe to tell me, then let it go.

This concerns me because in the past he was throwing up and having the runs every time he went back to his Mom's house, but would be fine the second he got back to us. They moved in with his maternal grandmother who he hadn't known in the past and he got better, but now they have moved out without her again.  He also has huge issues with his speech and angry outbursts.  His speech is probably 2+ years behind and he has a reputation for having large "temper tantrums" that are very hard to stop at daycare/camp.

I'm so worried because I love him to death.  It's hard to figure out what is going on.  On facebook she has lots of pictures of them doing awesome stuff together and he seems so happy but yet she does things like keeping him in shoes two sizes two small until he is crying because they are so tight.  This alone is upsetting but not enough for CAS to become involved I don't think.

What can I do to help him?  Is it possible he is talking about spanking or maybe a slap on the wrist or making it up?  He didn't act at all like it was a joke.

Can you give me a shortened version of the text?
<bot>: 4 year old says he gets sick at Mom's from his "feelings" and says "they hit me".  Use to throw up at Mom's only all the time.  What do I do?
