Is it normal to cuddle your mom?
Depends.It depends
Yes, cuddling your mom can be a normal way to show affection, though families differ in how physically affectionate they are. What matters is that you both feel comfortable with it.
Lots of people cuddle a parent, whether it’s a quick hug, sitting close on the couch, or a full-on cozy snuggle. Other families are more “love you, see you later” than cuddly, and that’s normal too.
There’s no age when affection suddenly becomes strange. If you and your mom are both comfortable and it feels caring rather than pressured, you don’t need to overthink it. And if either of you would rather have more space, that’s okay too.
