My comment was in answer to what the OP wrote, it wasn’t harsh either usually or unusually.It was surprise that in this pandemic a grandma was going to do ‘childcare’ ( the wording the OP used) for a three week old baby. A few posters were equally surprised.
This is an opinions forum after all.
If you think some of us will believe that, you need to give your head a wobble. If you didn’t have information to give, then why say anything? Your post was horrible and not at all kind to a new poster with a problem. Opinions weren’t asked for - information was.
