Milestone Mondays!- 18 months-24 months!

It’s been awhile since I’ve posted a Milestone Mondays post, so I’ll continue in order discussing 18-24 months!  The reason I post about typical milestones is so that parents pay attention to how their children are developing and to discuss concerns about possible delays with their pediatrician.   Make sure to scroll to the bottom to see the list of activities you should be concerned about for this age to discuss with your pediatrician.

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.

The main fun things that are happening between 18-24 months include:

  • your child is talking more and interacting with you more by using 2 word phrases and pointing and should have at least 50 words
  • your child is exploring their environment fairly well and walking independently without tripping in familiar environments, and is starting to walk up/down stairs with your supervision.- if your child is still unable to walk without assistance, please see your pediatrician to determine cause and possible referral to PT
  • your child is beginning to feed themselves using utensils and holding regular cups
  • your child is beginning to draw lines/circles using a crayon
  • and of course, let’s not forget temper tantrums begin at this time! 🙂 Refer to my previous post to learn more about dealing with tantrums.
