Nesting
Nesting is a common practice usually done by omegas, in which they gather up a bunch of pillows, blankets, clothes, and other soft things and lay them out in a way that forms a comfortable “nest”-like shape.
Omegas often nest when they’re stressed, in heat, pregnant, just after giving birth, during storms etc. Usually in highly emotional, or vulnerable states.
Nests are usually in the bedroom or in a closet, and anyone who is not family, mated to the omega, or a very close friend, will mostly likely not be able to touch the nest, as the omega is afraid they will “mess it up”. But allowing their mate in their nest can be a very serious and stressful step in a relationship, but is usually a necessary one if the couple wants to grow closer together
Overall, nesting is a very special and comforting thing for an omega, and it can help them embrace their dynamic.
