It's party time! Throughout her pregnancy, mama celebrated little milestones on her journey to meeting her tot — feeling a first flutter, seeing a first kick, etc. Once her lil one enters the world, there are endless markers to observe — each worthy of its own mini celebration. Here are 10 milestones worthy of smiling about during your baby's first six weeks.

Baby Meets Mom and Dad
Nothing is sweeter than capturing baby locking eyes with mom or dad for the first time. Newborns can only see about a foot in front of them, so hold your baby close while someone snaps the moment.
First Family Picture
It's an important moment to look back on, and all grown-up kids look forward to seeing a record of the first family photo.

Baby Holds Her Head Up
Sometime in a baby's first six weeks, she'll begin to hold her head up  on her own. It may only last for a few seconds, but it will demonstrate to mama that her neck muscles are growing stronger every day.

Umbilical Stump Falls Off
The umbilical stump usually falls off in baby's first two weeks . Once it does, mama can give her lil one a bath, can diaper without extra care, and can start using all of those adorable clothes she's received as gifts!
Baby Changes Facial Expressions
At even 6 weeks old, a baby can develop sound and music preferences . Sing varied lullabies and watch how your baby reacts. You'll notice that baby will communicate his favorites with gestures and facial expressions.
Baby Gnaws on Fist
Baby gnawing on her fists might be the sweetest and funniest action you'll capture in the first six weeks. As baby develops her motor skills, chewing fingers and fists is her way to explore and discover something new and different.
Baby's First Real Smile
You may have seen your lil one smile while you were still in the hospital, but the nurses (and your own mother) most likely told you it was gas. When your tot gives you a smile for the first time , you'll know it — and you'll celebrate it!
