DS was all sleep and no play up antil roughly 5.5 months. As a newborn he would be up, fed, changed and asleep again within 30-25mins and he fed four hourly.
It moved out to no longer than an hour awake time until 4 months and then 1 1/2 - 2 hours.

He now, at 10 months still sleeps 2-3 hours most sleeps and only a 54 minute nap before dinner.

Jazz is breastfed on demand, yeah? So if that works for her let her sleep by demand too! You are doing a fantastic job Leash, no need to doubt yourself!
