moment, BT I don't actually do a lot of activities with ds yet, mostly he follows me around asking to be picked up or plays with dd.
He likes to help me put washing in the machine or pull everything out of the cupboards. He also likes to help hang washing up which means on fine days it gets dragged across the garden or on bad days it gets pulled off the airer-this means I spend A LOT of time just undoing his 'housework'.
When I do do proper activities with him we play with bricks (I build he knocks down), I sing songs with him(mostly ones with actions like row row, if you're happy and you know it, heads shoulder knees and toes, pat a cake etc), I build the trainset for him to play with-he mostly just pulls it apart though but I am lucky because mainly dd entertains him for me! I have to say the playroom is a huge bonus too, it is set up so he can get to all his toys, when dd was his age it was all put away and I used to have to get things out for her and get something else before she got bored!
Colouring was a big disaster last time, he ate the crayons and had blue poo and he also drew on the wall. He seemed to enjoy making cakes with me and dd but it was VERY messy and next time I will definitely close all the doors to the rest of the house so he can't run off and smear the mixture everywhere! He has just got into trying to do puzzles (those wooden ones) but isn't into reading books together unless it is a noisy one ummm
