My baby girl 3.5 month old. Her weight is 6.100 gm and height 60 cm. She sleeps only 2 hours at day and 9 hours at night . But sometimes she sleep straight 6 hours should I wake up for feed each 3 hours by disturbing her sleep because her sleep is only 11 hours throughout 24 hours. But when she awake she is very active she wets diaper more than 10 throughout the day.
