DH is off this week and I'm not. Dd is 2.5. He's bored of being at home and asked me for suggestions of places they could go things to do. So far I have suggested:
Zoo, we have 3 locally
Park
Soft play
Swimming
Train to London to do the museums (we are 1hr 20mins away, but dd loves the train)
The beach, 10 minute walk from our house
Picnic somewhere
All have been dismissed as being a faff or places will be too busy because it is summer holidays. AIBU to tell him to either suck it up and go out or spend the next week sitting indoors/in the garden entertaining dd 
He has a car and although we don't have an unlimited budget we can afford a couple of days out if he took a picnic lunch.
