hi hun, you've gotten great advice already, just popping over here as requested
i'll explain my reasoning behind how we did it. we had a df at 10pm which was 50/50 whether he woke, 1/2am feed, 4/5am feed. we decided to drop the 1/2am feed first because we had a df but also because the lightest phase of night sleep is from midnight til 5/5.30am, so we wanted to teach him to sleep without a feed in the lighter REM sleep in which they are more likely to waken easily first (and also take longer to settle without a night feed). we then ditched the 4/5am feed, as figured we'd only have to get him back to sleep once and could then be up to start the day. and we still have the df which we will tackle soon, but because this is their deepest sleep phase of the night, it is 'in theory' easier to settle them.
with the first feed we dropped, my ideal feed time was 4am, i allowed 30mins grace to feed earlier. but anything before that (yep even 35 minutes) was a resettle, and we would resettle like pp described, until he fell asleep even if it went past the time i was planning to feed. that way there was no confusion as to 'is she going to feed me if i cry long enuf' or not. the first night was LONG, 1.5hrs to get him back to sleep, second and third nights quick resettle (under 15mins), 4th night regression, 1.5hrs again (this happened with both feeds we dropped), 5th night didnt wake.
dropping the 4/5am feed i reduced 2mins each night (1min each side) got down to 3mins each side and then dropped it. i started by picking him up for some cuddle time the first two nights to get rid fo the feed first, and then worked on settling him in his cot. took a few weeks for him to not wake at all at this time but i think there were some routine issues/too much day sleep/teeth at play there. he now STTN 50% of the time or needs a quick resettle at this time. i think i was helping him too much and sshh/patting longer than really needed so have backed off how much i help him the last two weeks and it has improved.
jean has a good point with the refluxing, my only other thought tho is that a df would be closer to when his meds are taken, whereas as it gets closer to morning he has been longest without medication (ie. more refluxy after the 4am feed), how is he usually after this feed?
i think the biggest thing, no matter what strategy you choose is to be consistent
more hugs hun
