I didn't get any routines started until 4 months old besides their feeding schedule which I regulated by 2 months. Now we have scheduled naps and activities and feeding times that work closely with what she naturally wanted to do. So for example we feed her a bottle at 6, 10, 2, 6 and 10 - the first hour after her bottle she wants to be entertained but tummy time makes her sick so we chose other activities with her during the hour until she wants to nap. Then when she wakes up we do some tummy time and other activities when she gets frustrated with tummy time. We also try to go for a walk once a day. Great for me to get moving and she gets some fresh air.
