I work 4 days a week and DS (3.10 yo)goes to MIL 2 of those days. I drop him off in the morning, she gives him his breakfast and takes him to preschool. He has his lunch at school and then she picks him up after lunch club. I pick him up at around 6pm so asked her before we made the arrangement if she could give him his tea. She was fine with this. I pay for him to attend the lunch club so she doesn't have to worry about giving him his lunch and he goes to my mums in the school holidays to give her a break.
Now DS has started to tell me this week that he doesn't have any tea at grandma's. I ask him what he has eaten for all his meals to make sure he is not exaggerating and he tells me what he has for breakfast and what he had in his lunch box but when asked what he eats after school at grandma's he tells me he has no tea but he might have had a lolly or something like that. Wednesday he said he had a bowl of ice cream and a packet of quavers!
I am really hacked off with this. I know its only for 2 days out of the week but he will associate having that sort of crap at PIL's house. DH hasn't really said anything about it but I feel I need to say something to her but don't want to sound ungrateful for what she does for us. DS goes to a CM for the other 2 days. We cannot afford to put him in with CM for the 4 days I work so she is saving us alot of money and she appears to enjoy having him.
AIBU to make an issue of this? If not, any suggestions on how I can broach this with her?
