Your beautiful little miracle-gro baby will be putting on a full ounce and a half this week.
And that's just the beginning! Within the next five weeks, they'll really be packin' it on as they start to gain fat!
For now, we’re pleased to report the addition of rapid eye movement (REM); a key component to any healthy baby's sleep schedule, that indicates they're now capable of dreaming.
Over in the dermatology department: your sweet lil bun's thin soft skin is very red, rather translucent, and a bit wrinkled.
Not to worry, it’s not some creepy premature aging disease. It's just their clever little body setting them up with extra space that will smooth out once your little one starts packing on the baby-fat. That won’t be for a few more weeks, though.
So, for the time being, your munchkin is still a little lean mean growing machine!
Lastly, the beginnings of what is commonly called “brown fat” is just starting to fill in to help your baby retain some body heat, which is crucial as they’re not yet capable of regulating their own body temperature.
