Even though I've been a mama for over 2 years and have seen all this once before, it's no less exciting to watch my big boy tackle all these huge milestones and knock them out one by one in such quick succession!
About two weeks ago, he was still army-crawling/belly lunging to move about, but had just begun sitting quite well without tipping.
Over those two weeks, [the two after he turned 6 months] he began
1) pushing himself into a sitting position on his own
2) truly crawling by moving his hands and knees (17 Oct)
3) pulling up to his knees on EVERYTHING and screeching to show his pride and pleasure
4) although for an entire week or so he's been threatening, by putting one foot on the floor while in the above position, finally this morning he pulled up to his feet on the dishwasher!!! Yes, as you can see he was quite proud!
