Mine are 8 and 5 now. Tips from experience:
We didn't allow late bedtimes at weekends and still don't. They are already asleep at 7.3 5pm. Nursery is tiring and they never lay in!
Rule of 7am = morning but not before. Gro clock is fab for this.
Lazy breakfast with one parent while the other lies in. Out by 10am though as they start bickering.
One of the following: farms, country parks, swimming, bit of food shopping (never a full shop though), cafe, meet friends for lunch, library, cousins' house, zoo, out on scooters etc.
Home for TV, splash in the bath and early to bed.
If weather is awful - icing and decorating biscuits, indoor picnic with teddies, make jelly and have a pretend party, print colouring pages, play doh, build a den and read to them in it, lots of cbeebies.
Now they are primary age they each do a club one day at the weekend and also get invited to parties which entertain them well. I don't have to stay either!! They can and will play together for half an hour or so. I found 8 year old in her room reading a book today- brilliant. They will also watch a whole film peacefully, can play board games with us, help with cooking reliably and eldest can get breakfast for them both if I CBA to get up. It's got much easier recently.
