The 'when to wake and feed' conundrum

One thing you get constantly told is to wake newborns every 2hours to feed and categorically don't let them go longer than 4. I have been going with the 2 hours in the day and 3 ish at night, but feel he can go longer and waking a sleeping baby takes more guts than a bungy jump imo!

We have a breastfeeding clinic on Thursday so will ask then, but there doesn't appear to be a hard and fast rule. I just don't want to end up with a dehydrated baby, but at the same time, I want him to get into the habit of sleeping as much as possible.

I dutifully set my alarm for 3.5 hrs this time and woke to super peaceful baby. I did my usual 'IS HE BREATHING' leap out of bed and stare then touch as that's not good enough and then decided to wait a while.

I got up and fidgeted around for a while in the bathroom and I could hear him starting to mess so I sat on the bed and waited on more feeding queues. He went to 3hr 50 mins and we making noises, chewing hand and squirming, so I am going to start going by his lead I reckon. He is a good weight, is gaining, although not fully restored yet and my milk is in.. So in theory, not an issue!
