My MIL and FIL look after DS once a week and occasionally at the weekend and have done since he was 1 (now 4.5). (They used to look after him twice a week but we already reduced this because of this issue).
MIL and FIL are fantastic with DS in many ways - he loves spending time with them and they love having him. He’s very lucky to have them.
We have always had some “ground rules” for when they look after him - e.g watch sugar intake, limit screen time etc. It’s not strict, essentially everything in moderation and we just ask them to keep us informed so we can adapt as needed.
MIL and FIL would admit themselves they are not the healthiest of eaters and have no desire to change this. This has caused confusion in the past where they’ve given DS something they think is healthy but we wouldn’t think is (e.g ultra processed, low calorie). FIL also doesn’t take well to being told what to do and can sometimes be a bully (which I admit gets my back up and makes it hard for me to back down). MIL is very unconfrontational and will go along with anything even if she disagrees to avoid an argument (but will make subtle comments so we know if she doesn’t agree).
FIL wants free rein to do what he wishes with DS when they look after him. He wants to spoil DS as that’s “his right as a grandparent”. Mainly this is give him sweets, chocolate, ice cream etc, buy him any toy DS wants etc. Whilst we understand this to a degree FIL looks after DS too often to spoil him as much as he wants to. My mum also looks after DS and it’s not fair on her if she follows what we ask when she too would like to spoil him more. More importantly, this isn’t fair on DS as he gets confused or upset when there isn’t a consistent approach and takes sugar crashes after eating too much sugar.
DS is getting older and is able to understand and verbalise more. This afternoon, he came home and told us he had 3 chocolate treats which they hadn’t told us about. We asked them and they denied this. DS insisted he was telling the truth so we questioned them more.
FIL got defensive asking if we’d been quizzing DS after they’d left - we did but only after DS initially told us. This has led to a heated discussion tonight as FIL says he should be able to do what he wants, he’s raised 2 boys who turned out fine, DS is only with them one day, we’re imagining the sugar crashes etc. He also thinks we should trust them and not question them (despite saying he doesn’t want to go along with what we’re asking).
We have outlined the reasons we’re asking them to follow our rules. Ultimately he’s our son but we have them there because it’s what we think is best for him. MIL is agreeable but FIL is grudgingly backing down. It’ll likely raise its head again in a few months as this seems to be the way it goes.
AIBU for expecting them to follow our wishes or am I getting too bothered about it?
