I was an Early Years teacher for years before having DD (and a good one!) I hope to return to it again it’s just a rather more flexible and less stressful opportunity happened to crop up when I was on mat leave and I took it.
Anyway, the point is I had all the ideas, my own tuff tray, tons of craft resources etc I’d built up myself and was quite passionate about play. I really thought I’d be the mum who was doing all the messy play, sensory stuff, elaborate role play etc. I loved all that stuff at work.
Turns out I don’t really like it in my own home, and from the time when DD was tiny I far preferred being out of the house with her.
We DO play of course, and draw and colour and cook and even occasionally break the play dough out, but I’m certainly not the natural I thought I would be. I do it because it’s good for DD and a bit of structure helps us get through the days.
I know you didn’t want advice OP, but someone else has said they were following for ideas so to them I’d say maybe look up the 5 minute mum on Instagram/ she has relatively inexpensive books too. There’s more stuff on phonics/ learning type things these days but scroll back to find the relevant age of your child - she doesn’t do anything with elaborate set ups or that take too long to tidy away. There’s also ‘play hooray’ although she seems to be all about empowerment and coaching stuff these days, but you can scroll back to the more useful play ideas again.
OP - if you’re happy with how things are and DS seems happy, and it does sound like you’re spending lots of quality time with him in other ways then crack on.
