You need a two pronged plan: firstly to prioritize your sleep and secondly to get ds in a better pattern.

So for your sleep, can you make Dh get up with the kids in the morning so you have an hour to sleep, or have a weekend catch up? Does dd go to any child care so you can sleep with the baby?

For ds, I think your plan sounds great. Perhaps he is sick or teething so needs extra comfort just this week? I would keep trying to just lie down with him, and see how you get on.

I know what you mean about leaving older child. Ds now mainly naps in the pram because I can't leave dd for too long unattended. Is that an option? I know lots of kids who only sleep in the pram in the day. One mum I know would just strap bub in and he'd nod off before she'd left the house because it was such a strong sleep cue.

Teaching babies to solo sleep can be tough for both mum and baby...you're building a beautiful relationship with your son by attending to his needs, but you need to look after you too. That's why I think you could address your sleep as the first priority before trying to 'fix' the baby.
