I agree with AJP, 2 hours at that young age seems too long to be up. My DD (5 mths) has only just started to be up for 2 hours and sleep for 2 hours. Sometimes she can't even last two hours up, particularly in the morning. For example, this morning was 1.5 hours up then she slept for 2 and a quarter hrs. From very early on she pretty much slept most of the time after she fed. Try not to think to much about routines this early on, for me personally it didn't work until she was older. Try to look for tired signs and within 5-10 mins, bubs needs to be in bed otherwise you'll find bubs will be overtired.
