The make shift playpen suits my little baby just fine, don't you think? My 'bigger' kids are awesome with their "babysitting" techniques!
I love this stage of sitting up un-attended but not yet crawling. I am so very smitten by this little guy...he is my buddy who is always willing to snuggle just about anyone and smile and laugh. Who said I didn't have enough love to share for a 6th baby? I bet that person never had 6 kids...
