Developmental Stages for Baby: 4-6 months – Eastern Idaho Regional Medical Center


– I’m Corwin Sutherin,
Pediatric Occupational Therapist at EIRMC and today we’re gonna look at some developmental milestones
for a four month old baby. The different areas we’re
gonna look at is movement, sensory, so vision and hearing, grasping patterns and some reflexes. So first of all, let’s
look at some reflexes. She has kind of, it’s a Palmer
reflex, which is appropriate. But it’s not as strong as if
she was two to three month. So she’s grabbing my hand. There’s still that grasp there
but she still can release. And at this age, four months, that Palmer reflex starts to go away. The next reflex we’re gonna look at, it’s called a poll to sit. So as I take her, grab her arms, I’m looking at her head control. And she’s keeping her
head right in midline. That’s good. She’s using a lot of tummy muscles. And as I go back down,
she’s good head control. And her head, nice, softly
goes back to the blanket. So those are a couple of reflexes that are good, good head control. Now I’m going to look at sensory. So as she sees the object,
she sees it with her eyes and she’s reaching and she
should be bringing her hands to midline, which she’s doing. As I take the object and
I move it to the side, she’s follows it and
it facilitates a roll. And as I go back to this way,
she follows it over there. And as I take it away, and then I (rattling) She’s looking at me. (rattling) What was that? What was that? Over here, she’s still
visually looking at it. And then she looks with her hearing. So she’s using her hearing. You hear that, that’s good. Okay now, let’s look at some movement. Let’s start with rolling first. See if we can get her to roll. So I’m gonna grab a toy over here. She’s real happy. She’s smiling. She sees that. So she rolls to her side, which is good. Four month old baby should
be able to start rolling. And she comes all the way to
her tummy, which is perfect. And now while she’s on her tummy, she’s reaching her arms out
and she’s bearing some weight on her shoulders and her
hands, and that’s everything that she should be doing. She’s got her hand up to her mouth. That’s good. Now I’m gonna see if can get her to roll from her tummy to her back. I’m gonna help her out a
little bit with this because at four months old a lot of
babies like to be on their tummy because they can use their hands and that’s the position
they like to play in. So I’m gonna grab this toy. I’m gonna move these a
little bit over here. Oh, spit up, that’s what babies do. So we get her to her side a little bit. And she comes to her back. Okay, alright. Okay she’s come up. She’s looking around. So with the grasping, let’s
look at the grasping next. Let’s give her a toy here. And these are all good, developmental toys where she’s definitely
not gonna choke on them. She’s holding it, bringing
it up to her mouth. So she reached out, brought it in. That’s something you expect to see. And she’s still holding it with one hand. So we looked at grasping patterns. We looked at some reflexes,
some movement patterns, and some sensory with vision and hearing. And some babies will typically
develop at different stages. Some a little sooner,
some a little bit later. And if you ever have any
questions or concerns about your developing baby,
contact your pediatrician.
