my oldest was crusing furniture by 6 months and walking by 9 months. He wasn't bowlegged and his bones didn't snap. He was, however a little top heavy and would topple over easily.
I, too fed him cereal by the time he was 3 months old. I got many tsk tsk tsks from mothers my age, but I paid attention to the old school mommas... they had been there done that. by 7moths old, I had done away with my son's plate (it only ended up on the floor anyway)and plopped his food right there on the table in front of him. He had toddler spoons and a sippy cup. That boy loooooved dirty rice
. His only allergy is shellfish.
