Mama_C - yay! Is the later nap helping? Are you letting him sleep for longer now?
Melissa - not sure I've reached you in time, but look at the positives - she slept an 11h 20 night, which is pretty reasonable at this age. OK its earlier than you would like, but she had a longer night so should be more rested. IIWM I would push as far as possible, 12.30pm absolute earliest but closer to 1pm if she will do it. Then I would allow her to sleep for 1h 45 absolute max. If its 1hr again then 7pm BT again, if its more, push her closer to 7.30/8.
stardust - capped nap is ok if your dd regularly pulls 12hr nights - its still 13.5hrs in 24 which is bang on average sleep needs. However, you may find she'll struggle to last the day on a 1.5hr nap if she had it every day. You don't know these things unless you try them, but I will admit hands down I was sure my DS needed a 1.5hr or less nap 2-3 months ago & look how he proved me wrong! That said, I was prepared to accept a shorter night (nearer to 11hrs) and was also prepared to wake him in the morning/from naps. Is that something you would be willing to do
Based on what you are wanting I would say aim for something like this:
Wake: 6.15am
Nap: 12.15-2/2.15pm
Bed: 7/7.15pm
I think you will need to wake her in the mornings if you want any chance of sticking to this. But it may send her into OT if she's been waking at 7am & you suddenly wake her at 6.15, so you may need to wake her say 5mins earlier every day/few days until she is getting up at your desired wakeup time. Does that make sense?
