Me too.
I do love the tiny toddler phase, there is nothing as heart fillingly cute as a child whose only recently learned to walk and the absolute trust they have in their parents, the way they get excited over ordinary things like a bird or a tractor or a swing...
However I would not go back to that phase for anything.
My children sleep!
They only wake me in the night if they're actually genuinely ill.
I went years without a night's sleep...
They also take themselves to school, stay home alone, take responsibility for their own homework (the older 2 - dc2 asks for help learning for tests but importantly he initiates it) the older two cook for the family occasionally, the eldest puts a load of laundry on if she needs something that's still in the dirty basket (need to work on that with the middle one). Eldest keeps her room beautifully tidy and regularly reorganises it (younger two don't...).
The older two make me a cup of tea sometimes even though they don't like tea themselves - middle one is most likely to do that. They take responsibility for knowing when they have football matches and checking whether we can drive them, whether we can give their friends lifts, whether they need to ask for lifts, whether their kit is clean...
Even the youngest can make himself breakfast or a sandwich and obviously his cold drinks, hosts his friends himself when they come over, can make phone calls using the landline and makes the calls to organise playing with his friends, with my permission and walks or cycles himself to friends in the village.
They're all very amusing and say some startlingly insightful things.
Them growing up and becoming independent means everything is going as it should. It's a good thing. It makes them feel confident and happy too.
Infantilising children is like wanting them to be ill or something, it's weird.
Mine still all call me mummy though
