Lo has this and hes now 5mths old almost 6 and yep it will grow , slow but it will!

Lo has curllies there lol

My son's hair fell out at 3 months and started exactly like that.

Happened to my DD shes 8 months now hers is almost grown back in. She didn't spend a lot of time on her back either but when she fought sleep she rubbed her head back and forth I think that's why hers did it.

Try positioning pillow with holy in the middle , looks like a heart

Normal! Ds is 6 months now and his hair is thicker so you can't really see it anymore.

Dd is 7 months old and still has a bald spot. Plus she sleeps on her tummy 90% of the time. Don't worry it'll grown back

Yep, it's normal to happen round about 3/4 months and will grow back.

This is normal

My second daughter had a line all the way around her head of baldness where she rubbed her head when she moved it, it was funny but looked strange because her hair was so dark. It grew back pretty quickly though once she was sitting up.

My DD currently have a bald spot as well. She have a good amount of hair so it's not really noticeable. It should grow back

Thanks girls, I guess I'm just worried out it being flat. When SD was little bm would just leave her in the crib or swing all day. Dh had 50/50 custody from day one. SD would scream bloody murder during tummy time with her daddy and I. We would spend his custody days trying to keep her on track and encourage proper head development. Unfortunately she suffered a few developmental setbacks, she didn't roll over for several months and didn't walk until well past her first birthday due to the damage bm caused. Now sd is 4 and thankfully everything has worked out developmentally. She's right on track.

My daughter developed a bald spot in the same place at around 3 months old.
She's 7.5 months now and the hair has started growing back in, it's now getting harder to see the patch.

My son came out with tons of hair and then lost it all after a few months..now he can grow a head full of curls. It'll grow back
