Huh? Oh dear, that would be a little insulting but hopefully she meant to be helpful. We are always learning in one way or another aren't we in our business? But if you have a parent who thinks you are stupid you are better off without that family. The poor child must be so confused with her busy parents but you can provide the stability for her and now that I have this bit of info I would suggest routine, routine, routine at daycare to instil that feeling of consistency for the child.
I've had parents in the past who told me they can't figure out how I keep the children on their schedules, even after 2 weeks of vacation. I keep telling them how important the routines are for the children and how they actually look forward to knowing how their days play out and what to expect next. 5 children falling asleep within a few minutes of each other daily is not an accident. Magic word - ROUTINE!
