For those of you with more than one child

This is a silly question but am I the only one who has decided not to bring my 3 year old swimming when I have both kids by myself (while husband is at work during the week)?

I have a friend who keeps asking me to come swimming at her house but that would consist of me going in the pool with my 3 year old and leaving my 2 month old in her bassinet/pack n play.. I don’t know how to tell her I just feel like I can’t come swimming this summer. It’s actually my friends mothers house and I think her mom would want to hold the baby while I’m in the pool and idk how I feel about that with covid

How are you juggling bringing more than one child to a pool by yourself this summer?
