Bloody hell OP, what sort of madness is going on on this thread?!
OP has cooked a load of food to keep in the freezer so it can be reheated and eaten after the baby is born.
Her DP is eating this food now. That is very wrong of him. He stupid is he that he does not understand “this food is for after the baby arrives?” What is more, he knows that OP has had an eating disorder in the past and she is trying her best to avoid what she knows will be triggers to stop eating again.
And now people are deciding that his motivation for eating this food with his son is that he wants to make some sort of point to OP that she was not thinking about his son when she did the batch cooking. So to teach her a lesson he’s feeding it to his son! What nonsense.
He’s feeding it to his son because he is lazy and it is there.
This is doubly stupid as it is food that is not suitable for a nursery-aged child, due to fat and salt content.
The child also eats a hot meal at nursery (where he is until 5, so will have that served at teatime) so does not need a full hot meal upon coming home. It’s clear that the idea post-baby was for the adults to eat the adult food after the child was in bed and the child to have some easily put-together, child friendly light meal between nursery and bed time. That is completely reasonable! Exactly what we have been doing with our son since he was weaned.
OP your partner is an arse and so are most of the people who have responded to you on here!
