Development Of A 6 Month Old
I have a few concerns about the development of a 6 month old little girl, Sara, I care for.
The first being that she has never rolled over. She is also unable to sit up. If I attempt to sit her up she tips over. Also, she does not support her weight on her legs. If I hold her under her arms and bounce her up and down on my legs her knees always stay bent. When she sits in her exercauser her legs are always bent. When laying on her back she does straighten and kick her legs.
She doesn't enjoy being on her tummy and is unable to lift her torso up using her arms. Her left arm stays straight by her side palm facing up.
Finally, she seems to at times not want to focus on a person’s face but will track a moving object just fine. She can say Dada and babbles. She also can smile. Sara reaches for toys and will immediately put them in her mouth. She can also wave, not at the right times yet, and is fascinated by her hands.
I'm not sure if I'm just being a worrywort...or if there is a reason for concern here. Please advise.
