Hey!
I am a single parent but I do sympathise - I only have one and sometimes wonder if I could cope if I had two. My child is very high energy though too - I think that makes a difference
my tips when I’m having a taxing week and am tired would be:
grab a mcDs drive thru for supper (it’s fun?) and a take out for urself one evening (finances dependent) to treat yourself
Soft play session/s to zone out a bit…,or is there a play cafe near you?
getting a few stickers and new bits for craft table (play dough?) to occupy your daughter in a tough or tired moment
planning a schedule for yourself ie morning/afternoon block activities even if it’s just park trips
As others have said - make sure you’ve got food basics in
if you’re sensitive/neurodivergent maybe it’s just the thought of overwhelm and stimulation all day?
if so - plan for places that are good for you as well as kids as far as poss, or get some ear plugs like loop for soft play :)
being solo means accepting things being rough round the edges and sometimes going a bit slower
shame (from entertainment respect) your kids aren’t into tv but maybe picking a film with your daughter if you think that would make a difference?
