..maybe a growth spurt!?
Around different "weeks" in a new baby's life they will experience growth spurts.. and unfortunately during these times, many babies will become much more fussy, sleepy and even more hungry! Sometimes they last 24 hours, sometimes they last a week! Try to soothe your baby, comfort them, and just cuddle time typically always helps!
I think Mini is done growing though. If that's the case, poor kiddo. She's barely over five feet tall. Welcome to the life of being short, sweetie.
