I was just going to suggest this! I don't like giving new moms advice, but this is honestly something I think everyone should try! At that age, I would try some kind of wrap, like a Moby, but when my dd grew out if hers we went with lillebaby carriers.
When she was restless I would walk around with her and just sing anything, and the combo of being so close to me and hearing/feeling the vibrations from my voice would put her to sleep quickly almost every single time. This worked for years. I finally stopped carrying her last year when she was 4.
An added bonus, it's harder for strangers to reach out and try to touch the kiddos.
