This is so strange and it just started. DS (who is BFed) has recently started sucking...loudly...on his upper lip. He is refusing the pacifier and he's not hungry. He is 12 weeks and it started a few days ago. I can't figure out why he started or what/if it means anything.
Have any of your LOs done this and does it mean anything? I considered maybe the start of teething because he has also recently started drooling and knawing on his fist.
Re: Sucking on upper lip
This. My LO has been sucking her upper lip occasionally for the last month, usually after she eats. It's kinda cute
