mum2be.. does she have a dummy? its tricky as nate has no dummy and i put him to bed and he cries for 3-4 min and then sleeps for 4 hours. just remember what ever habbit you start now... wont be easy later on if you want to change it..
If you are ok with it I used to put baby down and go have a shower.. they dont die from crying and they learn HABBIT so so so quickly.. Whatever work for you might not work for everyone.. So good luck!!
