Don't feel silly, @Una22 - it is absolutely normal to worry about how we are parenting, and it is easy to blow things right out of proportion. I wasn't a very Arts and Crafts kind of mum - they had colouring stuff but didn't use it that often, and I didn't get the painting stuff out often - and I convinced myself that this meant my children would utterly fail at school.
Looking back, I can see I was worried over nothing, but at the time, I lost sleep, thinking about what a dreadful mum I was. Suffice to say, all three did fine at school and university, and are now all working at jobs they enjoy.
So don't worry.
And if you are still worried - here is my best parenting story.
When ds1 was deep in the terrible twos tantrum stage, I had an awful evening, where he screamed non stop for over an hour and a half. By 8am the following morning, he was screaming again, and had been for nearly an hour, and I was broken. I rang dh in tears to tell him how dreadful it all was, and how I couldn't cope any more.
As he was reassuring me and calming me down, ds1 stopped screaming, so I ended the call and went to investigate. I found him at the kitchen bin, where dh had thrown away some uneaten tortilla chips, the night before. He was eating them out of the bin! But that's not the worst part. I looked at him, and I knew that, if I removed him from the bin or the bin from him, the tantrum would restart, full force, and I couldn't face it - so I let him carry on!
When he stopped eating and wandered off, I emptied the bin and found a safer place for it to live, and crossed my fingers that ds1 wouldn't get sick - and he didn't. Not a bother on him.
So - if you haven't let your child eat a delicious bin-snack, to stop a tantrum, you are doing better at this parenting lark than I did!
