some of you may have already experienced this: you take your perfectly happy baby to childminder, she stays there all day playing and then on the way back or back at home has the biggest meltdown and tantrum, mostly crushing it all on poor mum. Is it a phenomena? Is there a way out? Any tips? I have a 18mo and we just started with a childminder. She came back home and refused to obey anything I said unlike before and was seemingly annoyed at everything for a while.
