Kara - I just edited my last post. When I said don't push BT too far or she'll get OT, I meant to add that I've always done no more than 5hrs A to BT & that's always worked really well for us. That said, it was around the 18 month mark when he actually started to get UT with that. So....I'd probably see how she manages, PD at 6.30pm if she struggles, or nearer to 7pm if she is ok but no later. Then like you say, you can push the nap & BT later again at the same time.
Melissa. If she woke at 8.30am & you tried for her nap at 1.15-2.20 then I would say that without a doubt she wasn't tired enough. Oliver is doing close to 11hr nights usually & he can last 6hrs before his nap. So, your choice is to go with it, skip the nap if she doesn't want it & enjoy the lovely long nights, and she will nap as & when she needs it, or, you do like you say & wake her a little earlier so she is having a consistent length night & then she may be more likely to take the nap. I do think you'll need to aim nearer to 6hrs A though if you want her napping, so you could perhaps do 7.30am WU, 1.30pm nap for say 1.5hrs & 8pm BT? That would be a decent length day of 12.5hrs - what do you think???
If it makes you feel any better, Oliver had an 11.5hr night last night as we've had almost a week of earlier WU's & so we've cut his nap to 1.5hrs. Anyway, he was at nursery, & they put him down at his usual 6hrs A & he didn't settle for 30mins, & only slept 1hr, woke happy! So I am thinking when his night is over 11hrs, he isn't even tired after 6hrs. So its not all plain sailing here either! xx
