According to Dr.Harvey Karp, author of The Happiest Baby on the Block, Kaya has officially finished her fourth trimester and now is a legitimate infant (instead of a fetus living outside the womb).  His 5 S’s (swaddle, side, shush, swing, and suck) got us through the first 3 months quite successfully.  And I’m pretty sure Kaya is the happiest baby on the block – although I also think she is the only baby on our block.
