How can I be the best mum?

I have a 1 year old and genuinely curious of how I can be the best mum possible to him.

I try my best to spend time sitting, exploring and talking to him. I know how to make him belly laugh and I have never felt myself lose my temper with him. I do however sometimes allow miss Rachel or Mickey Mouse tv time when I’m overwhelmed (I work full time so balancing being a mum and working is tricky). I also don’t have a lot of money at the moment just with paying off some debt so I buy a lot of his things from Vinted - not sure if this makes me a bit of a crappy mum.

How can I be better?
