Thursdays are the best day since her DS1 is in nursery.
Train from Waterloo takes 55 mins. I would suggest we leave after 10 (after peak fares if poss) and avoiding rush hour in London.

July 17th
July 24th
July 31st
August 7th
Let us know if any of those are good or bad and then let's see who can make what dates.
