Rainy weekend suggestions please

[NellieTheElephant1]

I'm looking after my nieces aged 6 and 3 on Saturday. My DC are grown up and I can't remember what they enjoyed doing at that age. We need to be out of the house so the parents can get on with diy. Does anyone have any ideas of what the girls might enjoy (London)? Thank you!

the transport museum is good for younger kids, lots of stuff to do. kids go free, so you would just have to pay for yourself

Science museum. They have a brilliant water play feature. My dc loved it at that age.

Take them to see Frozen 2
Check the local library to see if there’s a craft activity or story telling
Swimming
Indoor soft play
V&A museum of childhood
Aquarium
There’s Christmas arts and craft sessions and face painting at Westfield uk.westfield.com/stratfordcity/entertainment/events/kids-christmas-workshops/56798

Thank you all!
