I told my 3 year old he could bring whatever toys he liked in the garden into the bath to get him into the bath and so my son brought his golf club My 1 year old and 3 year old was playing in the bath fine and so when I got my 1 year old out to dry him (next to the bath tub) I didn't notice that my 3 year old opened the golf club and started drinking inside.when I looked inside there was loads of black mould in it. He drank quite a lot. Should I take him A and E? Will be be okay?
