We've visited London a few times pre ds2 (me, dh & ds1) and absolutely love it.
I'd written off going again for a few years since the arrival of ds2 but I really want to go back again this Autumn.
I want to visit the Science museum so it wouldn't really be a sightseeing trip this time but a planned trip.
The baby will be 16 months.
We usually stay in a family friendly hotel on the outskirts, there's parking and it's a short walk to the tube. I'm thinking we can take a stroller and I'll just carry the baby in the sling for the tube.
