I can’t believe some of the comments on here, including someone saying it is dangerous! My late husband and I had my first GD from very early and remember once rushing to their house at midnight to collect her as she was sleepless and the parents had work in the morning. It’s been a pleasure and privilege to care for my GC (neither stays often now sadly due to being very bad sleepers, mum won’t inflict it on me anymore). We had no help at all when mine were young, I’m so glad I can help my own children. Grandchildren are wonderful, tiring of course, but they and their parents live in a very different world to the one mine grew up in. I didn’t work until they were 8 & 11 and that was quite normal.
