I called my son my "Baby Bean" now I call him my "Chunky Monkey" or "Lil Man." :)
My last pregnancy was with twins. They were both called little one since the only place I felt kicks is where they were closest and there way no telling who was doing the actual kicking. Lost my son at 23 weeks and delivered my daughter at 27 weeks. Still call her little one since she's still on the small side.
Gummy bear. Lol. First ultrasound the baby looked just like a gummy bear so it kinda sticked
I call mine my little clover. He's being named after a relative I was extremly close to, he was like my son, and he was murdered a few years back. His name is Patrick and he was born St. Patty's day hence Patrick. Lol. So I bought him everything clovers.. So I call Him my lucky clover or lucky charm
when I found out I was pregnant on an app it said my baby was the size of a peppercorn so I just shortened it to pep and never changed it lol
