Hi Y..
This is my advice to you: listen to you own gut.
You will hear many people giving you gratuitous advice, but YOU are the mommy of that precious child. if you want to pick her up to calm her or for her to fall asleep, please, please do and don't feel guilty about it.
This society is so bent-up on having our babies act like adults, it's insane. Remember, your baby has been in your womb longer than she's been out. she's still getting used to this world, and at 7 weeks, she shouldn't be expected to sleep like a 30 year old.
I always 'listened' to what my baby needed and even came to the point of bringing her to our bed to sleep. I can't tell you how many people told me I was damaging my child and turning her into a misfit. It worked out fine: she's not a spoiled brat, she's not twitching because of it. She's a sweet, caring little girl who now sleeps in her own bed at 18 months, and likes it!
You're doing great, and your being a great mom to your baby. Keep up the good work. The best way to care for your baby is to 'listen' to her and her needs. No guilt!
