I am going to stop deeing my baby and just need some mom advice.?

Good for you for feeding so long!!! I would stop too if they were biting though. My baby is 3 1/2 months old and I have had to stop feeding her unfortunately because she has to have soy formula. I think the hardest part is trying to find a formula that works if your baby is sensitive. With her being 9 months old though she may be more tolerant than a younger baby. I think at that age you can also start introducing other foods like mashed fruits and vegetables or baby cereals. Good Luck!
