Milestone Mondays!- 6-9 Months

Happy Monday!  Onto the next set of major milestones, with a focus on the gross motor milestones.

The major gross motor milestones that are reached between 6-8 months is sitting independently and crawling.  This is the time when parents have to start really keeping an eye on their kiddos and have to start baby-proofing the house.     Some parents think that crawling will happen miraculously even though they’re always holding their child.  I always stress to parents that they need to start leaving their kiddos on the floor more with a few toys out of reach so they can start moving!

Keeping with the template from my first Milestone Mondays,  I gathered this info from a site I brought up in a previous postCDC’s Act Early Campaign, as well as 2 tests/guidelines I use when assessing developmental delays- Peabody Developmental Motor Scales, Gesell Developmental Schedules.

Gross motor

6 months:

  • Rolls from tummy to back, and back to tummy.  Again typically tummy to back develops first.
  • Lifts their head when you pull them up into a sitting position, and should not let their head lag at all.
  • Sit in Ring-sit position for at least 1 minute by themselves (meaning, you shouldn’t have to have your hands near them)
  • Bear full weight on their legs when you hold them in standing (meaning they shouldn’t feel like their knees are giving out/buckling when you hold them in standing).
  • Begins to try combat crawling- crawling with their belly on the floor still.

8-9 months:

  • Combat crawls by themselves
  • Can turn around on their tummy while reaching for toys, called pivoting in prone
  • Begins to move into quadruped position on hands and knees and begins to crawl without tummy on floor
  • Sits for 10 minutes by themselves, and you no longer have concerns about them falling over in sitting
  • Can go from sitting to tummy and return to sitting independently
  • Can stand while you hold only their hands, and begins to pull to stand in their crib or along another surface

Fine motor

6 months:

  • Grabs objects using their palms
  • Tries to grab smaller objects like pellets, raking them in with their whole hand
  • Tries to grab a string with their whole hand
  • Starts to eat solids

8-9 Months:

  • Starts to hold objects with thumb and fingers, like holding a block
  • Begins to hold a rattle in their hand and shake it
  • Starts to try to hold their own bottle

Social/ Emotional

6 months:

  • Knows familiar faces and begins to know if someone is a stranger
  • Likes to interact and play with others
  • Begins to respond to other people’s emotions
  • Begins to notice themselves in a mirror

8-9 months:

  • Has favorite toys
  • May have stranger anxiety
  • May be clingy to familiar adults
  • Begins to feed themselves by hand
  • Begins to play peek a boo
  • Begins to imitate nursery tricks, like clapping, high five

Language/ Communication

6 months:

  • Begins to respond to sounds with other sounds
  • Strings vowels together, ah ah, eh eh, ah, eh, oh
  • Begins to respond to name
  • Begins to say consonant sounds bah, jah, dah
  • Begins to use other sounds to show they’re upset, other than crying

8-9 months:

  • Understands “no,” though I try not to use this word during treatments since I don’t want it to be their first word 🙂
  • Copies sounds/gestures
  • Begins to point

Cognitive (Learning, thinking, problem-solving)

6 months:

  • Looks around environment
  • Tries to get objects/ toys that are out of their reach, hence the beginning of crawling at this age
  • Brings things to their mouth
  • Begins to pass objects from one hand to the other in order to explore objects

8-9 months:

  • Starts to hit 2 objects together instead of only holding object in hands
  • Looks for objects that you hide

The following is directly from CDC’s Act Early site:

by the end of 6 months:

Act early by talking to your child’s doctor if your child:

  • Doesn’t try to get things that are in reach
  • Shows no affection for caregivers
  • Doesn’t respond to sounds around him
  • Has difficulty getting things to mouth
  • Doesn’t make vowel sounds (“ah”, “eh”, “oh”)
  • Doesn’t roll over in either direction
  • Doesn’t laugh or make squealing sounds
  • Seems very stiff, with tight muscles
  • Seems very floppy, like a rag doll

by the end of 9 months:

Act early by talking to your child’s doctor if your child:

  • Doesn’t bear weight on legs with support
  • Doesn’t sit with help
  • Doesn’t babble (“mama”, “baba”, “dada”)
  • Doesn’t play any games involving back-and-forth play
  • Doesn’t respond to own name
  • Doesn’t seem to recognize familiar people
  • Doesn’t look where you point
  • Doesn’t transfer toys from one hand to the other
