I keep a small notebook in my purse that i carry with me all the time, everywhere i go. it really isn’t as difficult as i thought it would be! i got lucky though, cause as soon as i decided to start keeping the record (pre-pregnancy diet) i found a new job as a nanny so i’m at someone’s house all day and it’s sooo easy to control my diet with my own food and formula around me. i also count protein and not phe’s. i can’t imagine that counting phe’s would be very easy… the protein for all foods is right there on the box!!
