Okay ladies I need help, my son is almost 6 months old and he chews on his hands a lot and he always without fail makes himself vomit at least 3 times a day. I've tried the nubby mittens, I've tried the regular clothes mittens, I've tried giving him things to keep his hands busy and when I can I give him his passy ( not in his Walker bc he throws it and our cat is obsessed with any type of nipple, shes eaten 5 so far.) I've tried teething rings and other toys but he always goes back to his hands.

Is there anything else I can do to keep him from making himself sick I'm at a loss.
