Starting to get into a routine with 2 month-old DD - she falls asleep about 10.30 - 11.30 pm and wakes at 9am ish (with one quick feed at 6ish). This works great for us cos she's awake when DH gets home from work for playtime and allows me to get some good sleep, we still get to have our dinner in peace cos she'll happily 'play' for half an hr by herself ... is there any reason we should try to move her bedtime to a more traditional 7pm ish?
