My sister mentioned that she had felt the back of her 3 yr olds head and it felt like there was a large bump. I felt it and it does feel like there is a flatter area then a large bump. She's not sure if it's always been there and she's just noticed it. There hasn't been any trauma. I've got myself worried as I recently heard about a child who had a brain tumour and the only symptom was a growth on the back of her head. I don't want to worry my sister as I tend to get a bit anxious. Anyone else's child have a funny shaped head?
