And I think it is lovely for the grandparents to spend that special time with their grandchildren..
I totally agree! My mum looks after DD one day a week and DD has such a close bond with her. It really is great for her to have such a close relationship with her grandparents.

I'm glad you have decided to do it - the first time is the hardest and once you have done it you will probably wonder why you didn't do it earlier
