Awake time between naps

Melissa
How long are your 6-8 month olds awake between their naps?  Our daughter will normally go longer on weekends because we are out and about doing things, but on weekdays our nanny puts her down about an hour and a half after she wakes up.  I'm wondering if we should start extending that now that she'll be 7-months in a week or so.
