I'm guessing you mean dummy insert 1st but if he wakes in say an hour just assume he is hungry?
Yes. I had a 5 minutes 30 minutes rule. And bear in mind I often couldn't see a clock (I'd turn the clock around any time I was exhausted), so these are not actual by the clock timings. They are approximate. The 30m could easily be 60m if I was knackered, but the basic premise remains the same.
The 5 minute rule may help with dummy pulling out too, now I think about it. Are you just putting dummy in and that's it?
5/30 minute rules were:
I'd spend 5 minutes resetting when first waking. That would be more than just 'dummy in, done'. It would be actively settling. From my bed, I'd cuddle into the cot. Arms around baby, dummy in. One of my hands holding baby's hands down (often in the crossed-chest swaddle position). The other hand/arm may be holding dummy in, or just cuddling around baby and putting dumny in any time it falls.
Then once fully settled, Id extract myself back to bed. You can do all this without opening your eyes, so going back to sleep is easier.
Then the 30 minute rule, again it's an approximation and could easily be 60 minutes. If baby wakes again in a time frame I feel like ^"you've not gone back into a proper sleep", then I expect to need to feed. So I'd put dummy in to give me a minute to come-round properly, scoot baby over to me, feed, return to cot.
The expectation is that in an ideal world you should be able to resettle baby back to sleep without milk. Rather than the expectation (in your own mind I mean) that baby needs feeding.
So if I had baby waking every hour, I'd do the half asleep resettle for 5 minutes every time. If baby went back to sleep in that 5 minutes, woke an hour later, I wouldn't feed I would be doing the half asleep dummy reinsert again.
I'd only feed if it was half an hour, or so, since resettle. Or if 5 minutes of resetting doesn't work.
Those pesky unrealistic expectations come back here though: if you are counting wake ups and noting the time of each, you could drive yourself insane with "augh I was awake every single hour last night ". Or you could frame it the positive way: "baby has only 1 feed / no feeds last night. Yeah! " and stop paying attention to resetting in the night.
