The First 3 Months:
- The size of the birth parents as newborns
- How long the mother carried to term
- The environment and culture of the birth parents
Height and Weight Milestones:
- A 5 - 7% weight loss during the first week of life. Breastfed infants may lose as much as 10% if their birthweight, but should be monitored closely by a doctor.
- A return to birth weight at around the second week.
- After that, a gain of about an ounce a day is normal.
- At around 3 months, he can be expected to pack on a pound a month, give or take a few ounces while his height will increase by about 20%.
Physical Appearance of the Head:
- Swollen eyes at birth
- Flattened ears
- A blister that forms on the lip from feeding
- Body hair (particularly so for preterm infants)
- Dry skin
- Enlarged genitals
- Smushed nose
Until 8 weeks, his movements are largely out of his control. Involuntary movements are without intention, so don't think he's pushing you away during a feeding or grabbing at a toy. It isn't until about 3 months that you may notice him gazing at his hands. He is starting to understand that those waving fists he sees aren't just another toy in his line of vision, but a part of his body. He may begin to shake a fist at your face or a toy that is nearby.
Sensory Development - Taste and Smell:
You can use his sense of smell to your advantage at time. He recognizes his mom's familiar smell and may find comfort in the odor that comes from a piece of her clothing during her absence.
Sensory Development - Hearing:
Sensory Development - Sight:
In the beginning, he can only focus on objects near to his face, no more than 15 inches away. His blurred vision has yet to master depth perception, and he shows a preference for bright, contrasting colors.
As far as the eye color, almost all babies show off blue eyes. It won't be until around 9 months of age that his eye color will be established.
Sensory Development - Touch:
There are studies suggesting that by appropriately responding to your infant's need for touch stimulation it can have a positive effect on his cognitive, social, and immunological development. In light of that, it is important for you to discover the unique ways your infant responds positively to touch and capitalize on this sensory need.
