Baby has been standing assisted and taking steps while holding onto a ledge or the couch. Today, he pulled himself up on my leg. He had a block in each hand. Then, he leaned back and stood on his own, unassisted. We were very impressed.
After, I kneeled on the floor and stood him up and he took steps towards me, but then his little legs got tired. We gave him tons of praise, and he was very proud of himself.
It's only a matter of time before his legs pick up strength and he nails this walking/running/jumping.
