Exclusively breast fed Bub at what age did you start leaving Bub while you went out?

I leave dad with expressed breast milk if I need to go out for a couple of hours. My baby is just gone 12 weeks old and we have been doing this for at least a month or more.

Since 3 months I’ve left bubs at home with my husband for 60-90 minutes

From 6 weeks old, I left bubs for about 3 hours once a week. He was fine with expressed milk in a bottle for a while and then started refusing it about the time he went onto solids. He's now a year old and can do about a day without me.

From about 6 weeks with dad. Then from 10weeks with nanna as I was returning 2 work.
