Have a 15 week DD who naps regularly through the day but only for 30mins at a time, and sleeps for one 2.5 or 3 hour stretch, then 2 or 1 hourly stretches during the night. This is not enough for me!
I'm finding I'm clumsy, dizzy, not losing weight because I have to eat constantly to keep my energy up, and driving extremely badly! Being clumsy is also not good when carrying my DD as I keep misjudging distances etc, and she keeps getting little knocks 
How do people cope with the sleep deprivation? Any tips?
(We already cosleep, but she wont latch on well when I'm lying down so have to sit up to feed her)
