Breast milk supply regulated at night

[edin16]

So the amount of breast milk you produce during the day is regulated by how much baby sucks during a period at night, I've seen and heard this multiple times. But what happens when baby starts sleeping more at night, does that decrease your day supply too?
My situation is: baby is 10 weeks old and still feeds (bf) every 2 hours, day and night. I can't sustain this nightly routine for much longer. We've tried a big bottle of expresses breast milk during the evening but that didn't help so my next plan is to top up with formula after night feeds. But if this works better then he won't be waking as much in the night, so will this reduce how much I'm producing during the day?

I thought it was more over the 24 hour period so if your baby feeds more in the day then you will make more in the day. So if baby has a big feed at 10am your body will make more at 10am the next day? Although I believe you are right in what you say that in the early weeks your supply is better at night.

With regards to baby sleeping at night I found that when I gave my bf babies formula it didn't make the slightest bit of difference to their night time sleep, although admittedly they we're going longer stretches of sleep without waking. I think sleeping longer I'd just something they do in their own time. I understand why you want to try something. Adding any formula will decrease your supply though which may make him feed longer/more frequently when he does wake up.
