Cheesecake for a 4 month old

[babyonboard]

This isn't a joke, really.
My MIL has an annoying habit of bringing round cake/chocolate sweets etc for DS (16 months)whenever she visits.
I've learnt to tolerate it and just limit what she gives him (she was once trying to feed him two slices of m&s chocolate cake at once!)
She visited us over the bank holiday and I was making coffee and came back to find her feeding my 4 m.o DD lemon cheescake. I was suitably peed off but she acted like she'd done nothing wrong.
Now DD is really sicky and I can't help wonder if this has caused any damage?

We visit my dh's nan (aged 90)once a week and she is forever trying to feed crap to our dd, we have to be on the alert the whole time. last week she tried to feed her a chewit. (She's 2.1yrs)No matter how often we tell her not to she just can't help herself. Ice cream, biscuits, chocolate etc etc. She once fed my nephew toffee (think he was about 8mnths at the time)

We deal with it this way: only visit after a big tea at home so our dd has little room for the junk even if she sneaks it to her, and accept any incercepted offerings saying dd can have them tomorrow as a treat, then eat them ourselves later(!!)

Luckily she hasn't started on our ds (6mo)yet, but there' time.

She says that in her days children were given a chocolate rag to chew, and she is desperate to do the same to ours! When we refuse she tells them "Ooh they don't love you, I'll tell you!"

Oh yes my MIL always says how she used to give tea with rusks in a bottle to DP when he was a baby and look how well he turned out etc etc.
I really don't understand this constant urge to 'fatten up' babies.
It can sometimes be really critical too, like when she moans that DS looks 'starved'.
He's 16 months and eats three good meals a day plus is constantly grazing. He's pretty tall but quite slender, but I'm comfortable that he eats enough. And stuffing chocolate cake down him won't do any good anyway. Grr, lol.
