hi, I'm an occupational therapist working in the field of children. we have so many cases with these kind of symptoms. you should check it for metabolic or neurological disorders. after that you should be referred to rehabilitation center for Physical therapy and occupational therapy to help your child to arrive the real developmental stage.
go as soon as possible...
good luck!
when was your last appointment? i assume at 9 months. the doctor wasn't concerned? it is possible that he needs physical therapy. i would at the very least call and consult with your ped. preferrably, he should be seen to rule out problems with low muscle tone, etc...
hi..i'm katherine from the philippines. my son also suffred from that kind of delayed. we had him check to so many doctors and check every possible cause. We just got a reason after checking his thyroid gland. We had his blood exmined (t3.t4 and tsh)and he got hyperthyroidism. Maybe you can ask your pediatrician about it and better go to a endocrinologist (specialized in metabolic disorder).
I hope this can help.
