Need advice

I’m getting my hair done tomorrow during the day. My friend was going to watch my LO but her kids still have runny noses (they were sick last week one having Hand foot and mouth). They aren’t contagious anymore but having runny noses Im not sure I want to chance it... however no one can watch my little one. What would you do?

1. Still take your LO to her and watch them while her children nap (friend is literally next door to hair lady)

2. Take your LO with you and let sleep in carrier (I don’t feel this is safe cause he’d be on the ground and they say they can asphyxiate)

3. Take your LO and wear them (would this even work)

4. Canceling isn’t an option as she doesn’t work on weekends and it’s so hard to get back into.
