Curious as to what your DC are doing this summer holidays. Mine is 4.
We have a family holiday first week of the holidays, then she has a week of ballet (half days), followed by a week at grandma's, then a week of singing (3 days), followed by a week of dance/drama (3 days). She doesn't swim yet so she'll do a week of swimming classes (just an hour a day). All other days/weeks are for playdates/pottering/family trips.
