PP anxiety or?

After speaking to my local feeding team, they've advised my daughter no longer needs to be woken up and fed every three hours and I should feed on demand instead.

Now I HAVE been feeding on demand, as soon as she shows her cues, I pop a boob for her and make sure she's clean and comfy.

But I've been setting an alarm for myself every three hours and waking her to make sure she eats. If she needs to eat 8-12 times in 24 hours, should I still be setting this alarm, checking and if she's asleep leave her be to kip longer or just scrap the alarm all together?

I'm definitely overthinking this, but we had a rocky start with her in and out the hospital and I want to make sure she's happy and well fed

(She's coming up 5 weeks and is over her birth weight. She doesn't latch long, but I have a fast let down and she chugs for at least ten minutes)

Sorry for the long post, thanks in advance
