Baby fever?

How do you know if you have baby fever? Weird question I know! I have an almost 11 month old and he’s still my baby! But when I see newborn babies or even hear the news of other women being pregnant part of me gets slightly sad kind of like I want that to be me again? Idk if this is baby fever tho?

PS I’m super excited for the women I hear that are pregnant. Like beyond elated! Just kind of weird mix of feelings I guess.

So when did you gals start having baby fever again after your first?
