Small world - I think we were the family of four (on the basis I didn't see any others with kids at all, let alone as young as ours)!
Conditions were good with plenty of water flowing at the ?23rd? switchback, as well as a trickle at the cables. There were some tiny patches of snow on the summit trail that could be used for water in emergency.
On the west side, as with every previous time I've climbed, there is water 0.5-1 miles after guitar lake at some springs beside the trail maybe 0.5mile before the 10 switchbacks. There's also plenty of good camping at this point just SW of the trail.
