Bel - I found The Baby Whisperer to be quite helpful. It's not Gina Ford-fascist but it does advocate a routine of sorts around the acronym EASY: Eat, activity, sleep, you-time...
Like some of the others, Ted has always been a good sleeper though I think this is so much down to luck...having said that, listening to your DC and beginning to understand the difference between hungry cry and wet nappy cry and tired cry etc is really useful.
For those with thirst, and as someone who had gestational diabetes last year with Ted, it's really not so bad if you end up getting it, it's so common these days even if you have no family history, low BMI etc. Symptoms for me were thirst and very bad thrush (as your body can't process the sugars so well) but I was able to control it with diet alone (i.e. no drugs, but I did have to prick my finger 6 times a day to test my blood sugars) and I have a great high fibre muffin recipe which got me through the irritating last few weeks when I couldn't eat much sugar or carb.
I've got a glucose tolerance test (GTT) booked for next week so I'll soon find out if I've got it again. If any of you do get it, I would say to lay off the Haribo and fruit juice and up your fibre and exercise!
Speaking of which Cookies - going to preg yoga today for the first time!! Will report back.
