DD is responsible, sensible and totally adores her little brother. This evening I had a shower, leaving the door open and asked her to keep an eye on him for 10-15 minutes and call me if she needed me. The phone rung while I was in shower and it was my friend. i called her back and said I'd been in the shower and she asked who was looking after DS. When I said it was DD she launched into a long lecture about how I'd put DS in danger and put too much responsibility on DD.
Now worrying whether she's right. DS didn't move from his baby gym for the whole time and DD sat next to him singing and playing with the toys.
So mumset jury was I being unreasonable?
