She sounds like a normal 9 week old baby to me - babies do cry, and in the first 3 months a lot of babies cry a lot (DS1 had colic and required almost constant attention the first 3 months, we could stop him crying by carrying him, jogging on the spot holding him, cradle rocking him or singing to him, but the second we stopped doing this, he'd cry).
Sometimes you can calm them down, other times you just need to hold them and let them cry whilst knowing you're doing the best you can. Even if you're holding her and she's crying, she knows you're there for her - you know yourself its better to cry with someone rubbing your shoulder than in a room on your own.
I don't know if your HV told you to let her 'cry it out' but she is far too young at 9 weeks for this approach. She's an infant, she needs snuggled and cuddled and carried about and sung to, and most of all she needs comfort and reassurance from her carer that she is loved.
Cry it out isn't recommended until a baby is at least 6 months old, and even then it will vary from baby to baby.
Babies are hard work, especially babies under 3 months, but trust me, you don't have long to go before it will start getting much easier - trust yourself - and give yourself a break - everyone's baby is unique - some babies are text book easy and seem to do everything effortlessly (and their mums will crow about this) others are hard work and they drive you to the brink of exhaustion (many mums are fearful to admit this, so often you get a biased view and think babies that cry a lot, sleep badly and need lots of comfort are 'odd' whereas they're pretty common - their parents just don't talk about it as much).
An hour of smiles a day at 9 weeks is fantastic - you're clearly doing something right :-)
