Hi there!
When you nurse your lo your body releases a hormone called oxytocin. The effect that this hormone has on you and the baby is to make you very sleepy! That's why you may also feel tired a few minutes into the feed.
I don't think overfeeding would have this effect on your lo but ... do you think you are over feeding? Does your lo eat a lot, very often?
Let us know if you have any more questions!
