My DD13 hasn't really adjusted to secondary school life and has developed anxiety. She's always been a bit chunky. Her dad doesn't really want to know anything about her weight issue. She's a size 16 and is 5ft2 She eats whatever she likes most of the time and she only spends about 3 nights with me. She definitely eats too much and doesn't like to move. However, since she started secondary school she has developed anxiety, and to me that's the priority.
So my DHs (not her dad) suggestion is that I simply control her portion size when she's here. I told her that's pointless and the change has to come from her and with the full support of her dad (which I don't have). In any case her anxiety is more of a priority and I will tackle that first. (School hasn't helped much so going the GP route).
DH called me inflexible and thought I should give his idea a go. I did it utterly pointless.
