We use grandparents twice a week, they offered and are thrilled about it, had a really honest chat with them before about everyone’s expectations and discussed different scenarios like them going on hols etc no surprises.
PROS -Child is in a loving environment and days out/ schedule is more flexible than nursery as just catering for one child.
You have more control over child’s diet - we send packed food for the whole day at GPs.
Sometimes child is too ill for nursery but not too ill for GPs as can just chill there like a home from home.
Child can take all own toys with them which they love.
CONS:
We have to book the same Annual leave as parents holidays from being the childcare so that we make the most of our A/L.
GPS could get ill and not be able to do childcare whereas nursery have many staff.
GPS may not be the type to follow your wishes regarding diet, discipline, screen time.
All in all I think GPs need to be the next best thing to you to be able to provide decent childcare, i fully trust my mum is that person, hence why our agreement works and no one falls out.
