Thanks again for your suggestions ladies. I felt like banging my head against the wall when I wrote that post earlier! We ended up going for a walk, and in hindsight I wish I'd gone for the drive option, but the environmentalist in me was saying it was all wrong! I walked for about an hour and a half and she didn't sleep! So i gave up, did my shopping came home, gave her dinner and put her to bed.

OP - I think you're right, I'm sure the vax is playing a part in it, and to be fair apart from the initial 8 weeks vax DD has never been sleepy after hers either.

Marcellus/Berrme - I can't believe I couldn't work it out, when it was slapping me right in the face... I am absolutely sure that overtiredness is playing a huge role in this, so thank you for pointing this out to me! We'd been to the park this morning and on the way home she wanted to go to sleep but I was talking to her to keep her awake because I wanted to get her out of the car first. She perked up when we got home so I gave her lunch too and it was about an hour after she'd been trying to go to sleep that she actually went. In reflection I wish I'd just let her sleep in the car and gone for a big drive or parked up and read a book or something. And the two previous days she fell asleep in the car on the way home and I transferred her to her cot, so no simple straightforward 'normal'days. I also think i am maybe putting her down too late at the moment, i probably should have tried to move her morning sleep gradually and let her find a natural time instead of jumping in there with one lunchtime sleep.

Tomorrow is going to be a simple and restful day at home. I like your idea of just putting her down whenever she looks a bit tired Berrme, instead of getting hung up on one sleep, two sleep, bedtime at seven yadda yadda yadda! My poor bubba, I just need to give her the right opportunities and think this out a bit more carefully.
