I'm loath to say it..... but i'll say it any way...... we followed a routine for ds - not from day 1, but by 6 weeks we had strict bedtime, and we began to leave him to cry - especially if it was a going to sleep cry (1st timers -odd as it sounds you really CAN tell the difference) - when he was about 9 weeks we started using the Gina Ford book... i never stuck to it rigidly, but I do believe it made a difference.
Now maybe he would have been a sleeper anyway - but at 2.5 he has his lunch and says "time for snooze", walks upstairs, has a wee, and goes to sleep for 2 hours. I can't believe he would have been this good if we hadn't stuck to a routine.
I know it's not the answer to everything, and it doesn't suit everyone - it worked for me because being depressed I really needed the routines to keep me going. I did used to get a bit (!!) stressed if things went awry and he didn't get to sleep at the "right" times, but this time round I know LO will survive - and yes - the Gina Ford book is out, and ready.......
Don't all hit me at once..
