Having to give my baby (half) brother his bottle in the night.
I was still at school and not sure how old he was, but certainly young enough to have me up in the middle of the night and down in the cold kitchen mixing his baby powder up. For reasons of her own sleep probably, my mother had him in my room along with another brother and as I was the eldest, muggins here had to do the honours. Still grates on me after all these years later.
Once made, I would balance his bottle on one side, stick it in his mouth, and crawl back into my half warm bed hoping for a little more sleep before school. Ironically, he is now a teacher!
Were these the good old days?
