Hi Rachel - just dropping in some support as my DD2 is almost exactly the same age & we're in the process of weaning night feedings too. A few weeks ago she was waking about 3 times a night & I was feeding her at least 2 of those, then I got it down to 1 (my guideline was to not feed before 2am), now for the last week its been 0 feedings. I would have been quite happy to stick with 1 but when she made it to 4am one night so I just tried resettling to see what would happen & never looked back. She has still been waking this past week, even though I'm not feeding, but its getting quicker and we had our FIRST ever STTN so I'm hoping its all a step in the right direction. It was really hard to start with & I was thinking OMG want am I doing feeding is sooo much easier & more restful! but it gets easier & its worth it in the long run. You can do it too
I love white noise, we have a little machine in her crib & when I go in at night to resettle I restart it. I think managing their daytime sleep (as well as you can with other LO's!) is important at this age to make sure they are tired enough at night. I also have to work around school drop offs and pick ups each day with an older LO which is tricky, I can post our routine if you think it might help.
Good luck!
