After many weeks of demand breast feeding and 20 minute naps (if we were lucky) we finally thought we'd cracked it when a few weeks ago we managed to get dd into a 3 hourly "routine", feed play for about a bit then down for a nap for about hour and a half. She hit 12wks last week and seems to have reverted back to her 4 week old self! Hardly napping and wanting to be breast fed to sleep, messing on the breast then wanting feeding again an hour later. To add to this I had her weighed today and she hasn't put anything on for a week despite gaining at least 8oz a week since birth (she did have a cold last week though). Any suggestions as to why this has happened and how to get back on track? DD1 has just started school and with school runs etc some sort of routine is a must.
