First off, you are doing a good job to give your sweet boy some tummy time and do what is best for him. You are following your motherly instincts to try to find out about this. It is good that you are aware of where your son is at, developmentally speaking. What does his pediatrician think? Here is some info about milestones: (keep in mind it is general, some kids meet them a little early, some a little late)
I'M 3 MONTHS OLD, I
turn toward bright colors and lights
follow moving toys or faces with my eyes
recognize or know the bottle or breast
respond to loud or new sounds
reach for and grasp toys or hair
wiggle and kick my legs and arms
lift my head and shoulders up while on stomach
smile back at parents or other family members
make sounds, like gurgling, cooing or babbling
I'M 6 MONTHS OLD, I...
turn toward voices
reach for toys and pick them up
roll over front-to-back and back-to-front
play with my toes
help hold bottle during feedings, if bottle fed
know faces of family members
babble, squeal, and repeat vowel sounds, like ooh, -ae, -e
sit by leaning on my hand
I'M 9 MONTHS OLD, I...
copy sounds or gestures
reach for crumbs or other small things with my thumb and fingers
move toys from one hand to the other hand
I straighten my arms to support myself when I'm on my stomach
understand the word "No"
The changes babies and toddlers go through are made up of different skills, like walking and talking. These skills, or developmental milestones, usually happen by certain ages. Although each child is unique and develops at his or her own pace, watching to see when a child reaches these milestones can help a parent know how their child is developing.
If there are concerns about how a child is growing and learning, consult with the child’s doctor or contact the DARS Division for Early Childhood Intervention Services (ECI) by calling the DARS Inquiries Line at 1-800-628-5115.(The information above was copied from the DARS website: http://www.dars.state.tx.us/ecis/resources/developmentmil...)
As a mother of 2 small children, and a teacher of children with special needs, my best advice would be to take action as soon as possible to make sure everything is ok. If your pediatrician is not concerned, or you call the number above and they say everything sounds normal, no sweat...If they are concerned as well, you can get some help for your little guy early on (that is best). Keep following your motherly instincts and loving that baby boy!
If you have more questions, feel free to send me a personal message.
