My MIL is genuinely lovely and supportive but OMG, she lost her mind a bit when we gave her her first grandchild.
Seems itās not that uncommon!
We didnāt live near them so they didnāt see the baby regularly, but when we did, it was like she needed to maximise the time she had by being FUN GRANDMA. Sheās loud anyway, but she would be shouting at the top of her voice, clapping, and singing nursery rhymes constantly. And I mean CONSTANTLY. She would even sing conversations. Itād go something like:
āDo you want a drink <starts singing and clapping, trying to get the babyās attention> DOOOO YOOOU WAAANT A DRIIINK?ā (clap clap clap clap clap clap).
My mental health was not good at the time (postnatal anxiety and depression) and the constant overwhelming noise, for hours on end, actually made me want to cry. The baby also got overwhelmed and wound up to the point she couldnāt/wouldnāt nap when Grandma was around, and then we had to face the repercussions of an overtired child
It lasted YEARS. Only when her golden grandchild reached the age of about 5 or 6 did she pack it in. Never did it as much with our second child, which was a relief, but she favours the first a lot, which is upsetting.
