1st child, dd, at age 6 months: from 8pm til 6.30 or 7.00am most nights. Sometimes would wake up a bit horribly early, like 5am ish.
2nd child, ds, at age 8/9 months: mostly 8pm til 6.30am. Sometimes would wake a little earlier. Just like DD, actually. Remember being horrified by DS. Everyone told me second babies were "easier".
Actually, now I come to think of it, neither child really slept for a long, decent stretch, until they went into their own room. I kept them in the bedroom with me til 6 months as per SIDS guidelines.
As soon as they moved out, we all slept better. Still glad I kept them in with me until 6 months though.
