my DS is 12 weeks tomorrow, weighs probalby around 8 kilos. over the last week he has begun to wake at 12.30am and/or 1.30am and occassionaly from 4am in the morning. he has stopped catnapping through the day, and used to go to not wake at night until at least 2.30am for a feed. when he wakes earlier he isnt hungry. is this a normal thing for around 3 months? will he return to normal??
