I don't know if it's because she's a girl. I think it's more probably because I was in slightly better shape the first time and was pickier about diet and exercise.
She's half a month old now and has held herself in a sitting position using the strength of her back and her arms as she pulled my hair. She was wobbly, but held it. I'm thinking she's at least a week behind her brother, but the hubby pointed out she was one week late being born, my son was two weeks late. I don't know if that extra time might help their development..?
She still needs her head supported when she's not actively doing something. LoL @ the speaking your mind. I said the first day, "wow, she's good at crying". Maybe the part where she's in her own little world until she wants your attention means she'll be less (of a pest?, needy?, demanding? How's the nice way to call a great kid who needs to engage someone 24/7?)
