Each little one is different when it comes to Activity Time, Naps and Night Sleep. I believe under the sleep sections they have a list of 'average' sleep requirements for each age.
My daughter is 10 months old and this is her routine which of course changes slightly due to her needs each day. Just as our needs change so do our babies needs.
6am wake
6-9am Activity Time
9am nap for just 30 minutes (if she sleeps longer than this she won't nap well in the afternoon)
9:30ish-1pm Activity Time
1-3pm nap
3-5:45 Activity Time
6/6:30 bed time
However some lo's this age can handle more A time and other less. It's all about following your lo's cues and knowing what's best for them.
Can you post your routine? Maybe we can help adjust it if you are having any problems with A time, naps, or night time sleep.
Thanks.
