What age did you start a bed time routine with your baby?
I recall with my first Daughter that we started about 5 months because she started waking every hour of the night.
My second Daughter is 4 months old and has started staying up and whingeing until about 10 at night even though she is really tired and has been fed, she just can't seem to get to sleep.
Considering starting a routine of bath, bottle, bed now but is 4 months a bit too early?
