I am at my wits end with DS (7 months old).
He has been teething since he was 6 weeks old and cut 2 teeth at 6 months. He is still teething now as he continuously tries to bite me! He was exclusively breast fed until around 5 1/2 months. He is now on formula.
He will not eat. He initially would eat puréed food and seemed to enjoy it, however now he will
sort of tolerate me feeding him a few spoonfuls of puréed food. He plays with finger food and eventually throws it on the floor. He gags and chokes at both lumpy food and finger food. When I am try to feed him he will push my hand away, move his head to the side and push his lips firmly close. If I manage to get some food into his mouth he will gag and spit it out.
Today he has not ate anything
. He continues to have his bottles. Developmentally he is on target.
He gets up 3 times a night for his bottle 
What should I do?
