DD is 6. At the mo, she is definitely in need of her downtime at the weekend. An average weekend might look like:
Saturday - chilled start to the day with some books, games, crafts, TV. Swimming at 9.45. Either home 10.45 ish or go straight to a farmers market or out for brunch.
Potter about in the afternoon. Games, crafts, bake, cook, science kits etc. Out on her bike or to the park if the weather is nice, indoor energy release games if not. Then nice dinner together, watch a bit of TV (Gladiators is a favourite at the mo!)
Sundays we tend to meet up with friends. If not, and its just us, we'll usually book an activity or something. This time of year, it might be climbing or a trampoline park if the weather is bad. Or get out to a local national trust if the weather is good. Farm parks etc in better weather.
Other weekends we might have grandparents visiting or friends and the weekends are a completely different shape.
