I.O.
S. ,i feel for you .my grandson did that also,what we did was
gave him a slice of apple or a toddler's cookie,something that he really likes ,gave it to him then changed his diaper. then after a few times when he knew he had to be changed ,we would start letting him know that if he was a big boy ,he would get
a treat,each time we would give treat to him later and later
now that he is almost two we don't have to do it anymore.the point of doing this is to get there attention on some thing they really like.we only had to do it for a few months ,then for some reason he just stopped giving us a headache lol
we also tried a frozen wash cloth,just wet and ring out leaving it twisted toss in freezer about 20 minutes or so,this is also great for teething he would chew on it and being cold it was defferant from just a toy ,if you would like to give him some thing other than food .good luck hope some things works for you .
