How do i protect my 4-month-old from choking and suffocation?

Keep out of reach: Remove hanging mobiles or toys before the baby can reach them. Keep cords, ropes, or strings away from your baby, especially near the crib. Ropes and strings around the baby's neck can choke him. Keep plastic bags and balloons out of reach. Use only unbreakable toys without sharp edges or small parts that can come loose.

Observe: At whatever age from baby to, older adult, small bites careful chewing appropriate food for age watch children while eating, since they will stuff anything and much in their mouth if allowed good dentition when of age don't talk with full mouth avoid drunkenness, and drugs as older don' be distracted while swallowing as a parent, know basic life support skills from aha heimlich etc.
