I know it's different for all, but at what age did your baby crawl? I think something is wrong with mine?

You're a horrible mother. Feeding your child twice a day is just asking for a fat, retarded child. Do you even know how many calories are in that formula crap? First off, you need to change the formula to skim milk (less calories). Second, you need to only feed your child once a day. Don't worry if the child complains of hunger pains, he will get used to it. There is nothing worse than a fat baby (or an ugly one but that's a different story).
