I am 71 years old, and up until,recently was looking after my 16month old grandson for one day a week, doing a ten hour shift.
I can quite honestly say that I have never felt so exhausted in all my life after they had left, and also the next day.
Just getting them ready to go out in buggy etc, then running around like a maniac trying to catch him to put him back in buggy. It's tiring.
Even now whenever I am asked to look after him, and I do enjoy it sometimes, but on the other hand, I know the feeling of exhaustion that will follow afterwards.
Ten years ago it might have been different, but my energy levels have depleted somewhat, especially as I am a poor sleeper.
All this combined, can make us grans quite anxious.
And of course, we all want to do well and please our offspring.
