Hi, is this normal? Just noticed my 15 month old has one side of the spine protruding when she sits. Should we see a doctor?

It looks normal! Does LO seems to be in pain while sitting or when you touch that spine area? My 2yo also has that spine protruding out.

Looks normal. I have it as well. Both my boys too. If you are still unsure take her to the doctors

Don't worry. All seems fine. As long as there is no swell and no pain. If say it's okay.

I also notice My 2 year old son has that kind of spine and I’m really worried😔

looks normal to me, check with the doctor if you have concerns
