London folk - Least busy time?

[NotAGolf]

We're taking our kids up to London at some point in the next couple of months. Which time would be least busy out of the these two options? (I'm aware it will be busy at both times!)

- Midweek during the Easter holidays
- Weekend outside of school holidays

Main things we're doing will be natural history and science museum.

Thanks all. Kids are only 2 and 5, but the eldest is into dinosaurs hence the trip to the history museum. A trip down the river is a good shout too. Finding things to do isn't the problem though, there's loads to do, I'm just trying to avoid the crowds.

Early morning on the weekend sounds like the best option, although it will take 1hr drive plus 45mins mostly on the northern line to get to South Kensington, so can't get there crazy early.
