I feed my 4 month old baby near 10 to 12 times a day. He always hungry. May I give any solid food to him?

Define hungry. You don't need permission to feed your baby.We don't recommend solids before 6m but this varies with the doc. If your kid consumes > 32 oz formula/day, solids may be needed. Some misread a kids finger or pacifier use as indication of hunger, it is not. The pleasure of chewing, sucking, nail biting, etc. Is a self soothing skill. If your kid is fluffy you may want to slow the feeds.
