Congratulations.
My youngest, of three, is 3 in Jan so a similar age. I've been through this age twice before but each child is such an individual its learning whats right for you and them. DD sleeps well, would benefit from a bit of a nap but resists and does her best impression of a temper tantrum if I try to put her down.
Currently we have lunch at the table then a drink and chopped up fruit in front of a film lying on the sofa for quiet time. A couple of days a week she'll drop off, a couple she'll rest and a couple she'll resist all rest and late afternoon i'll strap her in the pushchair and fast walk her on the school run when she usually drops off. DS2 used to always drop off in the car.
My favorite bits of advice are...what ever it is, its a phase (its a coverall, good or bad don't get to settled cause it'll change)
And parenting is a dictatorship. This ones from my dad and sounds a little harsh but is a reaction to people calling their DC their little friends. I think children are happier with clear boundaries. The boundaries are for each family to establish but they need to be clear and consistent from their dictators.
DD likes to colour, her brothers didn't at this age, she plays play dough and with building blocks, she uses cutlery reasonably well but struggles with her knife. She brushes her own teeth after we've done a basic brush. She is starting to dress herself and puts on her own coat/ boots to go out. She loves playing jigsaws on a touchscreen interface (tablet/ desktop). She loves feeding the ducks and splashing in puddles. She's not potty trained (i need to get on with it).
With food I'm trying not to stress with DD. She has eating well days and not eating well days. So long as she eats across the food groups I within reason don't fuss. For example she can't leave all her veg and then ask for biscuits ten minutes later. Fortunately she loves veg so tends to be an all or nothing girl.
