Some of you might know my middle son has dyspraxia. I also have a 18m baby. When the baby was born he had a very deep dimple by his bum. My middle son has this two and I was told its a form of spina bifida. I said I had taken tons of frolic acid even before getting a bfp. I was told it can be genetic. Found out my sh has these dimples and this week mil told dh she has them. The baby had a tongue tie, I then found out so does ds2. I read up on midline defects then. Now I know my ds2 two sides of the brain can't communicate normally and mid line defects keep popping back to my mind. Just interested as I guess it makes little difference - but could this be a genetic thing? Faulty gene somewhere?
