We've been doing a dream feed with our DS from about 6 weeks old. He is now 9 weeks. We have had a limited amount of success with this feed - sometimes works, sometimes doesn't.
I'm interested to know who of you out there does one and whether they work or not. I think the idea of them is great - fills them up without having to wake them, but I'm not sure if we'd be better off without one. DS wakes up anywhere between 3-5 hours after one but then won't settle for the rest of the night.
