my DD is 4 weeks old and an absolute delight. she sleeps really well, feeds really well and generally very happy and lovely.... until dad gets home from work! from the min he gets home till about 10pm she's gen just cranky, cries a bit, wont settle with dad, sometimes screams when he picks her up. she is better with me but he's starting to get a complex lol! do all babies get cranky at that time of day?
