DD sits around being miserable for 8 hours, clearly.
They do messy play. They play in the garden. They read. They have time to themselves if they want it. They play alongside other children. There's a play kitchen, play shop, blocks, puppets, dolls/babies, soft toys. They do activities relevant to the time of year (eg Easter, Christmas, Valentine's, other cultural holidays and festivals). When it snows they bring it in for them to experience and they explain why it melts and where it comes from. They draw and paint and play with playdoh. They do activities that help with their fine motor skills. They decorate cakes, biscuits etc. They have dance parties.
She's come home with cards she's made for us for every celebration possible. Sunflower seeds she's planted. Cakes she's decorated.
They ask for things to be completed so they can do things relevant to them. Such as family trees, their pets etc.
She is busy all day doing so many things she enjoys. She comes home covered in sand, paint, mud from the garden, bits of playdoh, marker pen, glitter, glue. And she runs out beaming and excited to tell us about her day.
There's an app that they update with what they've been doing, what they've eaten. I even know every nappy change she's had.
You used nursery for three months. Did you never ask on pick up "what have you been up to today??" so you knew what he was doing?
