my heart is full

this morning, milo was playing on his tummy while i got dressed and made lunches.  penny came into the bedroom to grab a pacifier for him because he was getting fussy.  a few minutes later, she came to find me in the kitchen to say - "mommy, please come feed milo, he must be hungry.  i tried giving him his pacifier, i checked his diaper and it's not wet, and i gave him lots of pats and snuggles so he wouldn't be lonely, but he's still crying.  the only thing left is being hungry."  this child.  it's her last day of being four, and she is taking the most amazing care of her brother.  i hope she knows how much i appreciate her - i try to tell her all the time, but it's never enough.
