M has only been doing about 1.5 for her nap when we have done 1 nap days but she does do a longer night then. Last night proved that as she had a 1.5 nap from 2-3.30pm (plus 30 min am) and then woke at 5.45am today...we do need to get to 1 nap now, just scared of the inevitable OT. I actually think M is quite low sleep needs though.
