In the beginning, it may seem that all they do is pee, poo, eat, cry, and sleep, but gradually, week by week, you will see growth and change in your baby. Review this list of newborn developmental milestones to see how your baby is doing. Newborn Physical Development In the beginning, you will notice that your baby uses jerky, uncoordinated movements that are sporadic and out of their control. If it seems like your newborn is pushing away your breast as you try to feed them, do not assume they mean anything by it. Movements in those early, early weeks are not intentional. However, as they reach their 1 month birthday, you will begin to notice a little more control over their body. Movements will still be jerky, but you might see them begin to bring their hands to their mouth with a little more intention and control. 1-Month Movement Milestones You can be watching for the following milestones during this first month. Arm movements appear jerky and shaking Raises hands near eyes and mouth Turns head from side to side during tummy time Head flops back when unsupported Clenches hands into fists often Has strong reflex and startle movements Vision and Hearing Development It can be upsetting to notice your newborn's eyes crossing. But this is a completely normal aspect of newborn vision development. Your baby is still learning to control their eye movements. As they age, they will grow out of this somewhat comical behavior, and you will be able to get some nice newborn photos. Here are some milestones you should see for the development of sight and hearing. Focuses on an object about eight to 12 inches away from their faceGaze wanders frequently, or eyes crossPreference for black and white or highly contrasting objectsPrefers to look at faces rather than objectsHearing is fully matureMay recognize some sounds or turn to familiar sounds or voices Sensory Development Using smell and touch can be remarkably effective in calming a fussy baby. Certain smells and touches that are familiar to your newborn have a way of soothing them (and you). Some milestones for the development of a newborn's smell and touch are: A distinct preference for sweet smells versus acidic or bitter smellsRecognizing the scent of their parent's breastmilkPreferring soft fabrics to coarse materialsBeing calmed by gentle, meaningful touches rather than jerky, unexpected handling When to Check With a Doctor If your baby misses a milestone, bring it up with their doctor. Your pediatrician is your partner—never be afraid to call your doctor if you have a concern. If after day 3 or 4 you notice any of these signs of a developmental delay, seek medical attention. Problems with feeding, for example, could lead to dehydration. Sucks poorly or has difficulty feedingFails to blink at a bright lightCannot focus on a nearby object that moves side to sideDoes not often move arms or legs or appears stiffAppears to be floppy and lacks muscle toneLower jaw trembles frequently, even when not crying, cold, or excitedFails to respond to loud sounds Your baby's pediatrician can evaluate your baby and, if necessary, refer you to a specialist. Early intervention can help make sure your baby is developing well or receiving treatment for any health issues. 1 Source Verywell Family uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles.
