Toddler sleeping schedule - what’s yours like and some advice?

Zaza

My baby is 20 months. I observed when she was bout 15/16 months, she would sleep for 10-12hrs, and after 4-5hrs from when she first awoke, she’d get a bit sleepy (yawns indicated this to me - that’s what I took from her yawns anyway). I’d put her down for a nap and was successful in doing so all the time. She’d sleep nap for a max of 3hrs and then be up. After 4-5hrs from the nap, she’d be yawning and I’d put her to sleep.

Now my husband seems have it in his head that if she’s sleeping 10-12hrs and napping for 3 hours, there’s no way she’d be sleeping “on time” so he’s just constantly making us sleep later and later and later and making it like 6-7hrs after her nap to go to sleep. Doing this, I’ve found sometimes I can’t put her to nap “on time” or at all (maybe 10% of the time” and then I’m scared when she finally sleeps, and sleeps at 9pm, it’ll be a nap and we’ll all be up at midnight, as that has happened in the past

Is what I was doing fine or is it better to do what my husband is doing? I still breastfeed her so naps start with nursing and then her sleeping and waking up for a little feed when she changes positions, as well as night time sleeps.

I’m so tired and in pain from always being on my side for nursing and I’m finding this newer schedule to not really help this.

Additionally, he’s keen on her watching cartoons and I have observed she’s very fussy, naughty, not sleeping on a day she’s watched cartoons eg Peppa Pig or Pink Panther.

I’ve asked kindly several times to please not let her watch cartoons to help me (and because I don’t think it’s of any benefit at this age) and he always agrees but then a few days after, we’re back to “baby, do you want to watch Peppa pig????” And baby saying “YEH!”
