TBH, things haven't gotten any better. We went to our health visitor who suggested that she's hungry, so we upped her solid feeds to give her supper as well and we are now supplementing her 7 pm bf with a bottle. Last night she took 200ml (7oz) formula at 12.50 and woke 3 times with a dummy reinsertion. Then since 5 has been very wakeful. I tried giving her water, then gave up and gave her a small bf. That sent her back to sleep for about 30 minutes. Now in the last 20 minutes, I have given her gel, teething granules and water and nothing is calming her.
I have tried varying the naps. I have extended her morning A time to 3 hours and that has improved her morning nap to 1.5 hours. But there are often things that need to be done (for example grocery shopping, when she has fallen asleep on the journey, much too early) or I have been going to my mother/baby support group (to keep my sanity) so the afternoon nap is often divided up. I have tried putting her to bed earlier or later. But she still seems to wake up at 5 or 6. I can't figure out what is wrong.
