Tristen at 2 months would be up until between 9pm-midnight. No matter how often he did (or didnt sleep) during the day. Now ( 91/2 months) hes down anytime from 8-9pm and sleeps thru till 6:30-8am . You just gotta do what works for you and dont beat yourself up about it  Tristen has got better after he got onto soilds...
