Cos my DS has been like this for 3 weeks now, and is only 16 weeks old! He's been great until then - only slept through once, but was doing 5+ hour stretches which was fab. He's now waking after an hour or 2 after going to bed at 6.30pm (he never, ever used to wake before 10) and then is feeding between every 1 -2.5 hours...(a few days ago he did a 4 hour stretch and i thought that was a sign of things improving but sadly not)
I'm waiting for this 'phase' to end but am beginning to think is whole cycle is messed up!
I have tried streching out his feeds in the day, feeding him often and no difference. DH does a bottle at 10.30-ish but even this isn't helping like it used to.
