My son is 8 months old and I’ve tried everything he just keeps spitting all his milk and cereal from the bottle he has now..which is a regular baby bottle (nuk in the pic) what is a good bottle for a baby that old still drinking formula and stuff? He drinks apple juice, water just soaked when I give him a bottle., I’ve even just barely cut the nipples so that he could ge the cereal though the nipple and he just bites though the nipples..Suggestions
