Grandchildren visiting

Have you tried playgroups/toddler groups?

We bought second hand high chair etc.for a few pounds each to keep at our house.

Have you tried advertising in shops like Age Concern. Or baby clothes shops. You need to target potential grandparents.

I know you said when this is all over, but I honestly think that people will be vary wary of using anything that they are not ultimately responsible for securing hygenically and would be reluctant to hire stuff to be used by grandchildren.

Our DiL brought her own high chair, and toys for her LO, even though we had plenty here from when the older grandchildren were younger. we acquired things for them, new car seat, second hand toys from charity shops but we washed them and were sure of their cleanliness.
Just a thought nowadays as I think things are different.

Charity shops sell them so cheaply though i m not sure you could compete
Most people buy them and then bring them back for resale when outgrown Even brand new items sell very very cheaply

My group of friends had, between us, everything required for visiting grandchildren. It was sometimes difficult to know who had the stairgates if they were needed as they got used for people with visiting puppies too.

I wouldnt hire stuff - I would buy or borrow!
