Dd turning 5 soon. She always loved playing with the play kitchens when we went to toddler groups and things, and loves the 'home corner' in Reception. We never got her a play kitchen at home because our house is small and we just didn't really have room. I found like a wooden play oven in a charity shop for her once, and we tried that both outdoors and in and she honestly couldn't have been less interested so we didn't bother.
Now talking about what she wants for her birthday and a kitchen has come up. We're hopefully moving soon to a bigger place so should have the space - there's a conservatory we've earmarked for a playroom (and if it's a few months down the road I don't mind cramming it into our current place for that long - especially as so much of the toddler stuff has gone now we can get it in ok).
I think she probably would still play with it, role play is her thing, though I don't know if she'd get that long out of it? We do actually have a 'mud kitchen' type one in the garden, which we're not bringing as it was a cheap thing that's pretty much falling apart, but maybe we could upgrade that for the new place instead? Again I wouldn't say she's had loads of use out of that. She very much has form (probably like all kids) for loving and desperately wanting something she'll play with at someone else's house or elsewhere, and entirely losing interest once it's in our home.
How long did your kids play with their kitchens is I suppose what I'm asking!
