Girls, hi! Could you please share some advice/experience? My child is one year and three months old, I'm working with a 2/2 schedule from 8 am to 7 pm on weekdays, I leave him with my mother-in-law, he loves her very much, she takes good care of him (he doesn't even cry as much as when I'm with him ??). And here's the thing, will my absence affect him negatively in any way? Who took care of him when he was a year old? Thanks for your answers!
