DS2 is 3 weeks. During the day he sleeps and feeds. During the evening and night he does the same. But less sleeping and more whinging. What he wants is cuddles with me. So I take him to bed and we all get some sleep. DH thinks DS2 needs to learn to sleep in his crib and to tell night from day. I agree in principle. But not yet. DS1 got it by about 8 weeks with a bit of help from gina ford from 6 weeks.
