What happens if i don't breastfeed my child? will a baby be okay with just formula?

Should do fine: I've never had a breast baby be allergic to the mothers milk, which can be a problem with formula. However, today's formulas are balanced nutrition for a growing baby. These are much better than the bovine home made formulas of the 50's to 80's and will assure baby can grow. You miss some of the benefits of breast milk, but you must do what you need to do to get through parenting.
