There are several options for parents who want to prevent spit up problems. I have already named you the main possibility, which is the proper bottle. Your next moves:
Don’t overfeed your baby. Since they can’t explain to you that he is not hungry anymore, it is one of the hardest tasks for mothers. You may try to feed your baby with small portions but more frequently instead of several times but until they spit up;
Try to help your baby burp each time they eat. You already know how to do this. Just get rid of gas bubbles from the stomach;
Don’t play with a child actively after the meal. You can’t do it even with adult people. Try to wait for at least an hour.
