Needy 8 week old

My lo just turned 8 weeks today and oh man since Monday she’s been so needy! This is completely new, for naps all she wants is contact naps which is so tough, Monday we played this back and forth game, I would put her to sleep and place her in the swing and she would instantly wake up crying I’d continue to do this back and forth. In the swing or bassinet I tried about 10x got to the point she was over it, screaming crying was pretty tired but was so mad she was fighting it at this point. It was so bad yesterday I let her sleep in my arms majority of the time oh the thing is too she’s picky she needs to be a certain position and rocked, so she slept better and was more content today is the same she just wants to be in the arms. This is ridiculous because my DH didn’t get home till 6pm we have a 10 year old I can’t even cook for her! How long is this going to last???? Any personal experience

Also before getting pregnant I’ve always experienced back problems now with her it’s way worse, my back stings and I feel like crying…
