This happens please do not worry this is a natural reflex

If I sit breast starts leaking automatically

So firs t try feeding your baby in every 90 minutes just let her suck breast normally but do it in every 90 minutes and see if she is taking it slow or again the same problem is happening try for 2-3 days at least

Sure will try this

Here what you can do is try to express your milk out first and with help of a small small spoon and bowl feed your baby once she takes few spoons then let her to the breast she will take it slowly because what happens when the baby is very hungry they will try to to forcefully feed and they will suck the brest very fast either the child is very very active and is getting hungry in every 1 hour try these two approaches that feed your baby exactly in in 90 minutes of the last feed and see if there is any change
