O I'm also sleep obsessed. My dd used to literally sleep anywhere it was great I could go out all day, meet my friends for lunch and she would just sleep happily in her pram.
She is now 19 weeks old and she is so aware of her surroundings she tries to stay awake if we are out, or, she will just drop of for 10 mins or so, resulting in a grumpy baby.
I've read loads of books, gina, baby whisperer, healthy sleep etc and tried to not get too bogged down in routine. having said that though she definately sleeps better at thome in her cot and she really is grumpy when she is overtired.
I was getting bit stir crazy though, staying home al day every day was really doing me no goodso have made a compromised loosish routine that works for us.
I usually wake her at half seven (bliss, she has just started sleeping through again) and about an hour and half after she wakes she is ready for a nap, this is usualy 1 to 2 hours. Then after another 2 hours she naps again hopefully for another 1 to 2 hours. This is all over and done with by about half 2ish so we tend to go out then as she still needs catnaps in the afternon, she cant really handle more than 2 hours awake. So then she sleeps on the move, in the car or pram.
I must admit I would much prefer to go out
earlier but its a compromise and my dd is much easier to handle in the evenings.
So anyway after a long waffly post (told you Im sleep obsessed too!) in answer to the op for my dd naps have been really important and she does well on a loose routine. I found the baby whisperer really helpful.
Mind you i have no idea how I would handle another baby, vcant imagine a toddler would put up with sitting quietly at home until half two every day!!
