My 11week old baby girl (breastfed) is still a little all over the place and i'm not sure if this is something i should be concerned about ??

If anyone has an 11 week old breastfed baby i would love to hear about what they are doing !

- catnaps during the day for 40minute sessions
- trys to go back to sleep but can't so is grumpy
- eats about every 3 hours or a little less if unsettled
- goes to bed somewhere between 7.30 and 9.30pm and sleeps for 3 1/2 - 4 1/2 hours then for 2 1/2 - 3 1/2 then for another 2 hours maybe in the early am hours then after that catnaps all day.

She is not getting enough sleep and im worried !
