3w old awake too long/really long feeds

Nadia

My 3w old only sleeps about 12hours in a 24hour cycle. I breastfeed her shortly after waking up. She takes more than an hour to complete a 20min feed.

She just takes loads of breaks and at times falls asleep etc.

With this taking so long, winding and diaper change and then struggling to put to sleep again, we fall into this vicious cycle where she is overtired and fights sleep. This morning she was awake until next feeding, then fell asleep 4mins into it.

I don’t want her sugar levels dropping so not sure whether to wake her and keep trying to complete the feed. Also worried about my supply if not feeding.

Any advice on getting out of this awful cycle? We are both exhausted, it’s the same at night if not worse.
