My dd is 7 weeks old and cries a lot! Don't remember my ds being like it as a baby, I could put him down on his gym or bouncy chair for hours and he was happy but dd just cries when put down and I haven't got the time to hold her all day long! I don't want to carry her in a sling either as I like to promote self settling and being content with at least a little bit of alone time.
On the plus side she does settle herself to sleep at night and only feeds once in the night now then goes straight back to sleep so it's not all bad just cries when she's awake!
