I don't know the answer/s Entreat, but can you put him in a sling/carrier and take him for a walk? Archie settles really quickly in the carrier or HAB. If you can't take him outside, can you wear it inside and walk around the house?

FWIW, Archie has had some really unsettled times recently too, fussing for the boob then rejecting it just as quickly, then sucking on anything that moves, then fussing, farting, etc etc. I hope you and Jack can get some rest soon.

for you hun.
