My wife has said many times that our son is so cute and adorable that she wants to gobble him up.
Why do mothers sometimes feel an urge to bite (or tightly hug) their children?
It's just a phrase used to stress how much she loves her! She's not going to do her any harm:)
I sometimes have a tiny urge to bite my LO's ear when she's on my arms being cute and sweet. I never do it though. So perhaps there is something literal to this phrase, as we tend to kiss and hug and cuddle with our kids.
because the default human response to cute things is to gobble them up!
it probably stems from the fact that kissing and nibbling on babies will make them giggle and thus make you more prone to play with them :)
