My little boy has started sitting on his own at 6.5 months! I'm amazed at how quickly he got the hang of balancing the top half of his body.
We simply tried putting him in a sitting position one evening before bed - That's when we took the first two videos below.
The third video was taken one day later. You can see the vast difference in how stable he became. :)
I still can't put him sitting down without sitting right next to him because he's not stable enough to hold his weight without supervision. But oh boy, seeing him take this little step of progression, my heart swells with pride! I can really see how parents are proud of their children just because they are their children.
