My EXH had our DS who is 9 at the weekend. My EX did ask when I was dropping off "what age was it OK to leave the kids on their own?" I replied "not at 9 years!".
So instead of leaving DS on Saturday morning he got him up at 5.30am to take him to his swim training session at the local pool. My DS sat on the side of the pool for nearly 90mins playing on his father's ipad before he joined him in the water for the last 30mins at 7.30.
DS has played down it - saying that he likes playing on the ipad (of course!) but eventually added that he didn't think it was very good parenting and was tired all day Saturday!
I personally am not happy for this to happen - it is far to early for him to get up. My EX won't pick him up until 7.30pm on the Friday (also due to his swimming) and it is 45mins back to his house so he not exactly getting to bed early either.
What can I say - my EX point blank refuses to listen to me or anyone else when it comes to doing his own thing!
A bit of background - until recently my EX was married with 2 small DDs but is now separated and so in the past left DS with his stepmother when he swam in the early morning.
