My DS2 is a few weeks old and ww are doing a lite version at the moment to try and get good sleep principles going... Mainly in terms of naps, putting down awake where I can and not snacking too much etc etc. my first son started at 16 weeks but would be interested to hear when you followed to the letter as it were. Mumsnetters who don't like routines or gf please don't post as I don't want to get into the whole debate! TIA
