As I write this, he's finally nodded off on my lap - but he has been up since 1.45 am, cluster feeding and chattering. Yesterday he cluster fed from 3 pm until 11.30 pm, having had a 1 hour nap from 1-2 - before that, he'd been up since 9 am. He slept for 3-4 hours at a stretch between 4 and 5 weeks old, after we introduced a 'top up' bottle of EBM last thing at night. However, since 5 weeks, he's slept a maximum of 3 hours in total a night - mostly in 1 2 hour stretch, then lots of 10 min catnaps. During the day he will only sleep in his pushchair or the sling (but he's over 13 lbs, so we avoid the sling as he's killing my back) for maybe an hour at a time. Other than that, he's catnapping. This means I can't catch up on my sleep, so I'm getting increasingly exhausted and weepy.
We have tried introducing a vague routine, using a dummy, my DP taking him to sleep in a different room (thinking that the smell of my milk is waking him), swaddling (this just infuriates him and results in furious screaming until the swaddling is removed - he even did that in the hospital after he was born when a midwife swaddled him expertly!), a dummy, me cutting out all caffiene from my diet (dangerous on 2 hrs sleep!), formula 'top up'. What else can we do? Oh, and we're co-sleeping, as the cot appears to be a magical baby waking device
Also, we calculated that he's sleeping 6-8 hours in every 24. Is that normal? He's very alert, and chatters to us when he's not feeding - he doesn't scream/cry a huge amount, and when he does, the only way to stop him is feeding him anyway.
