I feel like I might need to get a little perspective here but this really winds me up.OH had a call from his mum to say she was popping round and he asked her to come fairly soon as the kids would be having their tea. She's just turned up and while I was upstairs has given the kids a bag of crisps and a full tube of Rowntree's each. I've obviously come down and told them straight away that they can't have them but ended up giving in on the crisps as they were half way through and she kept saying "oh they're only a small bag, barely puffs of air." My OH thinks it's no problem and I should just give the kids their tea later but it really bothers me. She does this all the time, especially giving them sweets before bedtime which I've told her time and again make them go hyper. Should I just let it go as a Grandma thing or am I right to get wound up. Be gentle with me, it's my first post!
