Help!!!

2 week old will only sleep in my arms and being rocked. I also have a toddler and I can’t tend to him because once I get up baby cries. I have tried wearing him and he hates it! He also hates his swing too. I’ve tried colic holds too and it doesn’t work as well. Any tips would be appreciated! My toddler is misbehaving and it’s hard to parent him when I can’t even move.
