How old is your DS @Wfdg? just turned 2 or closer to 3?
It might just be your wording but you’ve said you “managed to get him to nap”...is it an effort to get him down? I only ask because mine turned into a nightmare to get down for his nap. Once he was down he’d sleep for a good couple of hours but to get him down was a bit of a battle. Stopped trying to get mine to nap and only put him down if he asked for one and our days are 100x better. He’s still an early riser but more 6am than 5am and he doesn’t very often wake during the night now. I know you said you’ve tried tweaking the naps etc but could worth a shot!
I think the playing with toys just comes with time tbh, or finding that thing that he loves 😬 Mine is also 2 (28months) and some toys hold his attention for a minute or 2 and other stuff he will sit and play with for 20 mins.
Obviously they’re all different but mine absolutely loves anything he can build/make - MagnetTiles, Duplo, Kinetic Sand, PlayDoh etc. He also loves role play type toys like his toy kitchen & food, doctors set, toy hoover/cleaning set and dolls house. I get it being lonely though, really, I do! DH works offshore so for 3 weeks at a time it’s just DS and I at home and I can feel a bit like a kids entertainer at the end of the day 😅 I also fall into the trap of feeling like he needs to be entertained 100% of the time. Like if he’s not laughing and being silly then he must be miserable 🙈 but I’m sure that’s just my own insecurity talking and me wanting to be the “perfect mum”.
With getting him involved with the chores etc, mine did take a bit of practice. The first time I tried to Hoover with him helping he screamed the whole time because he just wanted to stand and hold it 😅🤣 Now, we take turns lol or he uses his toy one while I use the big one. Laundry, he’ll “help” hang it up, or he’ll load/unload the washing machine. He gets a dry cloth while I’m cleaning/dusting and I give him something to clean while I quickly wizz round doing the rest 😅
Mine actually isn’t a great lover of the swing park etc. We do go but he much prefers finding sticks and stones and just generally messing around outside. We tend to do more “toddler led” walks rather than anything else so I just let him lead the way and we do whatever he wants tbh...it might be finding sticks, drawing in the mud with a stick, finding puddles to jump in, throwing stones in the water etc.
