I have never heard of GF until I found this site, and have never followed a "routine" as such - when I say that, my children do have a routine but it is one that they have instigated (if that is the right word), rather than one I have tried to force on them.
DD is my third child (now 4 months)old and I feel if I followed the GF routine I would be fighting a losing battle.
My dd wakes at 7:30 in the morning, has a bottle and is asleep by 9 am (normally by the time I put her in the pram to take her to school, she is so tired, she snuggles down, looks around her as though to say "I know where I am" and before I get out of the front door she is asleep).
She sleeps until 11:30 when she wakes from hunger and has another bottle. She will stay awake until about 1:00/1:30 and will then start grizzling. I know she is now tired again so I lay her in her pram and she goes off to sleep. I get my eldest dd from school and baby DD has another bottle at 3:30. I find she will stay awake for an hour and then fall asleep again and won't wake until 6:30. This seems to be her grizly time (if you can call it that) - and she has a bath and bottle, ready to be in bed for 7:30. She then sleeps through until morning.
At 4 months she is only having 1 bottle of 7 oz four times a day.
When I mention to my HV about how much she sleeps, she said not to worry - each child is different and obviously my baby needs it as she does sleep through the night, even after having a lot of sleep during the day.
I know if I had followed the GF routine, my baby would be tetchy all the time because, I think, she is having too much sleep according to the GF routine but if my DD needs it and it doesn't stop her sleeping through the night, I am not going to keep her awake/wake her up before she is ready.
My doctor and HV don't seem to be worried about how much my DD sleeps - in their view she is spending all her sleeping time growing (she weighed 7 lbs 15 oz at birth and now weighs 15 lbs exact). Because, when she is awake (although it isn't that often), she is very aware of what is going on, she interacts (if you can call it that) with her brother and sister and she is very conscious of what is going on around her, they don't feel it is a problem. They said that when she gets a bit older, she will be awake more in the day.
