My 2 year old has had a flat spot the size of the human palm since she was 3 months.

I have brought it up to her doctor and she doesn’t say anything.

I always over think and think, “Well maybe she didn’t really feel the flat spot” and having anxiety already. it’s something I always worry about.

The best description of the location I can describe it as is when a gurl puts a ponytail up. It’s not due to sleeping position because the flat spot is above where the mattress where even come in contact with. Is this normal? Any other babies have had the same flat spot on their head and they’re perfectly fine?

Baby was born vaginally, never had any falls, and has met all milestones. It’s literally the shape of her head but why?
