I’ve got two toddlers (twins).
Once you’ve done the house proofing (get down to toddler level and think “how would I fuck this place up?”) you need to think about structure.
Early start, have a fun simple breakfast. Get them dressed after. Then some playtime for a bit. When they get destructive, shove on CBeebies.
At 1000 do a simple outing. Even just supermarket you fill the time. Or a park. But if it’s a park, make sure you have one adult per toddler. If you don’t, go to a park that’s enclosed by a fence and has only one gate. Remember to do a nappy change before the outing.
Home for a simple lunch. Playtime and cartoons for an hour or two.
Afternoon outing, even just for an hour. It’s all about structure. If they nap, then a car nap is the easiest way to get a nap.
Dinner around 1745: keep it simple. Pizza or fish fingers or whatever. And DEFINITELY a dessert. Aim for the win.
Every family does bedtime differently. For us, it’s In The Night Garden on the telly after dinner. Then into the bath for a wee splash. Then bedtime with milk and stories, maybe 15 mins.
Maybe they’ll sleep easily if you’re lucky. Depends on the kid.
Good luck!
