Testicles that is! Will leave last night's thread well alone and just say that we found the requisite 2!
Checked him in the bath tonight an could only find one. Checked him out of the bath - only one. He was lying across my lap in his jammies with his hands down there as per usual and I asked could I check again. He said I have 2. I tried - only one. He says - "you have to use 2 hands like this" and proceeds to show me and lo and behold he has 2! So yay!
PS Spoke to school nurse as I was at school all day today anyway and bumped into her and asked had she been talking to them about their bodies. She said "I actually went in to talk about accident prevention!" So I asked if DS had asked anything and she told me that yes he asked what balls were for! She initially thought he said "bones" and replied "to stop you falling over" and then realised and said they were for when he was a bigger boy!
So still loling about DS's asking what they were for in an "accident prevention" lesson and relieved that he has 2!
And still embarrassed by my stupid attempt at humour last night!
