I have to agree with Nicole..
I had a cat I bought for jaecy (ok she wa only 5 months old, but i said it was hers

) it did the same thing...jae wound up eating cat poo twice and that was it...the kitten went back to the store!
I dont think it will get any better--it will probably get worse once he starts moving about...good luck though!
ps...siamese cats arent good with kids, I work at a pet store and we tell everyone who wants them not to get one if they have any lil ones around. And they are VERY stubborn animals!!
