Currently going through a nightmare with 4 week old, for the last 5 days she's been stuck in a strange rhythm.
She seems hungry and cries the house down, we make up a large bottle as we have been for a few weeks but after drinking a tiny amount (15-30ml) she falls asleep and can't be woken up by any means (up to and including touching a cold apple to her cheek and the 'inception' drop). We lay her down and within 30 minutes she's screaming the house down again and the cycle goes on.
We know she's got a much larger capacity as when she was 3 weeks she was taking 70-90ml per feed and sleeping for 3-4 hours.
Is there something wrong we're doing or a medical problem that could cause this?
