Congratulations on your new bub. It's been a long time since DD was that little but I do remember that I was told to wake her every four hours for feeds and I know now I would not do that with any other babies I have because I felt it really stuffed her around, sleepwise. Also, sleeping and eating patterns can change often. Maybe he is going through a growth spurt or wonder week and is needing those extra feeds? I wouldn't expect a lasting routine of any sort this early on, but I think you're on the right track with keeping your bedtime routine the same. You are probably getting to recognise his tired signs by now, so I say just go with the flow and let him feed and sleep as he demonstrates the need. Sorry can't be of much more help, I just know I wish now I'd been more relaxed about the whole thing! Maybe someone else will have more ideas. Good luck!
