Well, this is what I did, I woke her after 3 hours of sleeping - at 6pm, then she had a shower with DH and a bottle. At about 7.30pm, she looked tired, rubbing her eyes and a bit cranky. I picked her up for a quick cuddle, then wrapped her and put her to bed. I swear, not 30 min later, she was wide awake, couldn't settle her, so got her up and just sat her on my knee whilst we watched tv in the dark and hardly spoke to her, by 9.30pm or just before we gave her another bottle and then she was completely zonked and slept through until about 5am, then gave her another bottle. She was a bit unsettled from being put down after the last bottle until waking up in the morning but I just patted her back to sleep.
This is driving me nuts, cos we just went away for 4 days to QLD and she was heaps better there, but now she is back to her old ways.
She has done the same tonight, up at about 5pm, I gave her a bath, bottle then she was cranky so cuddled her for a bit and put her down to sleep about 7pm. About 10 mins later shw was crying and we tried to settle her for nearly an hour to no avail - ranging from picking her up, patting her, stroking her head all until she is calm, then we walk out and then she just starts again. In the end I got her out of bed and she is under her play gym and my DH is entertaining her ATM but she is a bit cranky, probably cos she is tired. She used to go to sleep at 6pm, we used to feed her at 10pm , but then we just let her sleep and this worked for weeks, but then she started waking for another bottle and now she won't sleep from her say 6pm or an earlier / later bottle until her last evening bottle at about 10pm or fourish hours after the last bottle. We go to a one day sleep school session on the 31st of October. So I don't know if I should just wait until then or keep perservering with her. I don't think it is a growth spurt now, I originally thought it was but this has been going on for a few weeks now.
