S.H.
My Husband's niece did that.
She scooted EVERYWHERE. ONLY scooting around. That's it.
But, she did progress to walking at a normal age, although sometimes it seemed she'd rather scoot than walk, or rather scoot than stand up.
But, there was something about her that was also like she had other developmental... uniqueness-es/problems. It was hard to explain, observing her.
BUT, she is a normal child now like any other.
Her parents did nothing to "change" her and it was just the child's way of getting around. Some babies do this, scooting.
She would even scoot around in a cafe or anywhere where the parents were... people would stare. The parent's didn't care nor make excuses nor were they apologetic to the stares. THIS was their child and the way she got around.
Their child scooted around for a long time... besides it being "germy" and dirty on the floors, especially in commercial/public areas... well, the parents didn't care or mind.
Sometimes she would scoot around using her front hands too... and it looked like a monkey. No insult meant. But yes, people would stare and comment and thought the child was strange.
I don't know what else to say, but this is how my Hubby's niece was.
If your child has no other developmental concerns or physical issues... then I guess its fine. But it seems she does not like to sit-sit... since she thrusts herself backwards. Maybe she just likes to be mobile... or to scoot around on her own without being told what to do? Some kids don't like sitting in their car-seat or high chair either and they will thrust themselves backwards... its a kind of protesting. BUT, if your child seems "unable" to physically sit properly or per biological/physical normal movements and coordination... then I would say that is a concern.
All the best,
Susan
