Childhood Milestones: First 12 mos

Don't you hate it when you have that stupid question about how many teeth a child has by 12 months?  Or whether or not it's expected for a child of 10 months to be standing up without support.  Or is it with support?
And you're just staring at the computer screen like:




Seriously, who can keep that stuff straight?  Nevertheless, if you're studying pediatrics, you will need to know some version of this, so, I'll attempt to boil down chapters 3-7 of the ATI Nursing Care of Children edition 9 so that you don't have to.  Disclaimer: these are only the non-obvious facts.  So, "duh" facts like "plastic bags pose a suffocation risk," aren't included.




0-12 MONTHS

PHYSICAL CHANGES
-Posterior fontanels close at 6-8 weeks (the way I remember this is: since the baby lays on its back, it needs to close the posterior fontanels first).
-Anterior fontanels close at 12-18 mos.
-Weight: birth weight doubles by 6 mos, tripled by 12 mos.
-Teeth: 6-8 teeth normally come in around 6-10 months, and definitely before 1 year.

MOTOR REFLEXES (GROSS/FINE)
1 mos: Head lag.   Grasp reflex.
2 mos: Still has head lag.  Lifts head in prone position.  Holds hand opened.
3 mos: Slight head lag.  Can raise shoulders up in prone position.  Loses grasp reflex.
4 mos: Rolls from back to side.  Puts things in mouth.  *Discovers that thumb sucking is pleasurable.
5 mos: Rolls from prone to supine.  Palmar grasp.  (Note grasp reflex looks like palmar grasp, but one is a reflex.  The other is a conscious choice.)
6 mos: Rolls rom supine to prone.  Holds bottle.
7 mos: Stands with support.  Moves object from hand to hand.
8 mos: Sits unsupported.  Beginnings of pincer grasp.
9 mos: Pulls self to standing.  Crawling.  Coarse pincer grasp.
10 mos: Independently changes from prone to sitting.  Can grasp thin objects, like a rattle.
11 mos: Walks with help.  Can place objects in container.  Refined pincer grasp.
12 mos:  Independent sit to stand and vice versa. Tries to build a two-block tower without success.

COGNITIVE DEVELOPMENT: Piaget-Sensorimotor (birth-24 mos)
-reflexes mature into intentional imitative activities
-separation from others
-object permanence (9 mos)
-recognizes symbols
-Languages:
  -Discovers that people respond to smiling, cooing, crying.
  -Turns head to aural stimuli.
  -Pronounces single-syllable words, up to 3 word phrases made up of 5 word vocabulary.
  -Understands "no" by 12 months.

PSYCHOSOCIAL: Erikson-Trust vs Mistrust (0-12 mos)
-Trust if needs are met, mistrust if need are inconsistently or inadequately met, OR if needs are continuously med BEFORE being vocalized by the infant.  (Capable of learning delayed gratification.)
-Attachment/bonding (Reactive attachment disorder results from maladaptive or absent attachment between the infant and a caregiver, like if the child undergoes a long-term hospitalization.)
-Separation anxiety 4-8 mos.
-Stranger fear 6-8 mos.

AGE APPROPRIATE ACTIVITIES:
Short attention spans, solitary play, activates senses--rattles, pat-a-cake, balls, reading very short books, mirrors, playing blocks, brightly colored toys.

IMMUNIZATIONS (per CDC):

NUTRITION:
-Breast feeding provides complete diet up to 6 months, and continues to supplement through 12 mos.  Supply iron if breastfeeding.
-Give vit D starting at birth.
-Solids are introduced around 4-6 months IF there is control of head and neck, disappearance of extrusion, and interest in solid foods.  Appropriate to switch to table foods at 9 months.  Examples are: bananas, toast, graham crackers, cheese cubes, noodles, peeled chunks of apples, pears, or peaches.
-DO NOT GIVE citrus, meat, or eggs until after 6 mos.
-Bedtime feedings are the last to be stopped.

SLEEPING:
-Sleep 14-15 hours a day with 9-11 of it at night.  Pattern is established by 3-4 mos.
-Sleeps throughout the night, and takes 1-2 naps daily by 12 mos.
-Cribs: slats should be no more than 6 cm apart (2.375 inches).  Remove mobiles by 4-5 mos.


BATHING:
-Temp set at maximum of 49C  (or 120F).

SAFETY:
-REAR facing until 2 y-o or surpassing height requirement.
