lumpy head at 3 months old👀

Kayley • 24 years old, I have a little boy who’s 4 and I’m TTC my second baby!! 👶🏻
My son is 3 months and has slight flat head at the one side, I've also noticed that is head is very lumpy and his soft spot at back of the head is visible, should I worry about this, or is it normal for babies to have lumpy misshaped heads, I'm worrying so much😔 his missing hair makes the soft spot look a little worse in this photo but still so worried😭
