I had my first son when I was 20 and my second just two years later.
I did things by the book, but 'the book' back then was very different from the one they use now, so from a modern viewpoint it is easy to wish that I had done things differently.
For instance, once I had tried everything I could to comfort my eldest son (who spent almost every waking moment crying for at least the first 12 months), I would put him in his cot and leave him to it. Nowadays, that would probably lead to accusations of neglect, whereas back then it seemed appropriate and even 'normal' with such a difficult baby.
Also, as my boys got older, I was too quick to smack them for being naughty, something which I now think was, for the most part, pointless and unproductive.
Looking back , I definitely wish that I had dealt with those things differently.
However, both boys have grown up into loving, confident, responsible young men. and they have very fond memories of their childhood so I must have done something right.
One thing is for sure, I very different as a grandmother from how I was as a mother - but they are two different roles, aren't they!
