hello
i was washing my 2 year sons hair tonight and noticed that at the back of his skull it looked and felt like it had got quite a big bump on it (back bottom right) and then a smaller bump (back bottom left). I then felt my 1 years old head and my head and ours felt flat in comparison. He seems fine in himself but just thought that it seemed swollen in comparison with 1 year old and my head. what do you think it is and would you go to doctor. not sure how long it has been there as husband normally does bath/wash hair.
thank you in advance!! foxy
