London day trip

I would say it depends on your baby if you know they’ll be fine on the train for that long then I’d say go for it! London has so much to do for kids just even the gentle sightseeing is fun for them! But the tubes aren’t always pram friendly, I went with the pram and in some stations there are no lifts just stairs or the lifts were broken down, so I’d find that out first. I think it was around Covent Garden or soho stop I had that issue but I had my travel pram at the time so I folded it and just had to walk up the stairs 😩
