would have gone loony bonkers without routine
Also, on the subject of crying, I hated my baby crying for any length of time when she was very tiny, but looking back, very often, nothing I did helped her, she just kept crying.
My life improved considerably when I let her cry a bit more . Sometimes she just goes back to sleep (when napping). I'd say, for the last two months, I've never "rescued" her from the cot when she was crying, and she has always fallen asleep within fifteen minutes. She no longer escalates to being "frantic", just on-off whinging
My HV gave me an article published in australia saying that research shows, children who have been allowed to cry themselves to sleep (within reason) develop better sleep habits in the long term. I always felt this would make sense, intuitively, but there was the research to back up what I felt.
Some people have said I've been hard on my daughter, never having her sleep in our room, allowing her to cry a bit, formula feeding her, establishing a routine early. I can honestly say she is a very contented baby (everyone comments on it), always happy to amuse herself for periods of time, loves social interaction, doesn't cry much. She's usually a delight to have.
I've been slated on MN (even before she was born) for my decision for her to sleep in her own room, told I was "cruel", told I would probably change my mind etc. I don't regret any of my decisions though, it seems to be working out ok for all of us, though I know that a second baby might be totally different!
