Just do what YOU KNOW is right for the child and give litte or no inforamtion to mom or be very vauge....Yup she napped well today.
I've lied before "no XXX didn't nap" only asked if they did otherwise I didn't mention it. Next morning I ask "how was xxx night?" "OH she slept so well, I knew she didn't nee a nap anymore" meanwhile her kid slept for 3hrs :laugh: whatever!! Parents for some things I believe are in a need-to-know basis.
