Yes Twirl, DS (2 yrs 3 months) always seems to go a bit loopy when we stay in but he hasn't twigged that he can ask me to go out yet. Even so, I usually take him out pretty much every day.
Recently, he and then his brother (now 4 months) have had chicken pox so for the last 5 or 6 weeks I have pretty much been banished from parks, friend's houses, everywhere really. We are slowly going insane here. I think it's best all round to go out most days but if you want ideas on what to do in the house here's what we have been doing inside for these last few weeks:
He helps me with washing up, brushing, dusting, putting the washing on etc.
Water play in the kitchen on top of a big pile of dirty washing. Washing his toy cars.
Drawing, glitter glue pens, painting, stickers, playing with bubbles. Making pastry. Playdough. Growing some tomatoes and watering them. C beebies and Nick Jr. More C beebies and Nick Jr! Playing at some of the programmes we see (e.g. he has a toy plane and spends hours flying 'Auntie Mable' and her dog around the house to various places). He is recently obsessed with playing upstairs so we've been doing a lot of that recently. I've realised we do stay downstairs a lot and just the change of scene seems to go down well.
By the way, getting out does slowly get easier. As I've said, DS2 is now 4 months and we can now manage 9 o' clock comfortably.
3 little frogs: I try to dress DS in red/orange at playgroup and a couple of other mums at playgroup also do. Soon they'll all be wearing red and we won't be able to spot 'em!
