Hi
I have two sons, aged 18 and 6 months. Both do not want to take any kind of food. Elder one do not eat anything he is on milk, cerelac noodles and smooth paste of heinz. While feeding I need to hold him tightly and then feed him opening his mouth and with great difficulty. he even do not want to touch any type of food like chips biscuits snacks toffees chocolate, nothing at all.
He is getting stubborn, aggressive destructive hyper, sleepless,and insecure day by day. Please advise me.
Younger one is now 6 months and from last month he is not taking milk I open his mouth and feed him with syringe drop-wise. Its been very painful for me as well, dealing with them in such a manner. please help me.

Best regards
Tuba Khan
