It's been a couple of years since mine were in the toddler years but back then my days looked something like this (precovid, not sure how much will have changed wrt playgroups)
7.00 get up, shower, make dc breakfast, get them dressed, teeth brushed, etc
8.20 school run for dd (&ds 2x a week once he got his free nursery hours)
9.30ish take toddler to a playgroup (Mon, wed, Thurs), to the zoo (weather dependent), or supermarket shop. But I'd always try and take him out somewhere.
Get home no later than 12.30 for lunch then toddler nap (whilst toddler was sleeping I'd tidy toys, or do some laundry, etc) Hopefully there would be some time to sit and have a cuppa before ds woke up.
2.40 get out the door for school run to pick dd up
3.10 get home. Feed dc a snack. Have a play date with friends 1-2 times a week (it game me extra impetus to tidy up a bit). In the summer spend time at the park, winters were more inside. Try and do a bit of reading/homework with dd if possible. Once or twice a week dd would have an after school activity which I had to ferry her to.
4.30ish start cooking dinner put dc in front of tv
5.00ish eat dinner with the dc
6ish dh gets home, plays with dc, eats his dinner and then cleans the kitchen a bit.
7pm 2x a week go for a gym or plates class as my me time
Get home, prepare any stuff for the next day, get dc ready for bed, then crash from exhaustion.
I think it really helped that we had a cleaner come for 2 hours once every 2 weeks to do the big cleaning jobs. We'd always manically tidy all the toys away the night before she came. But it meant the house was totally clean once in a while which made it easier to keep on top of stuff between visits.
It also helps that there were loads of toddler groups locally so we tried lots till we found his favourites and I got to know some of the parents that tended to go to the same groups. Or if he outgrew one there would be a different place to go to
