a pea a day will keep the doctor away

Yesterday I brought Jack to the doctor because he's been having a bit of a runny nose...then he started getting a cough...and then a hoarseness/wheeziness sound that kind of bothered me. It all turned out his is absolutely fine...everything is still upper respiratory thank goodness. Anyways, I asked the doctor for suggestions about his sleeping or lack there of at night. She suggessted the "Ferber" method I believe---its when you go in at intervals while he is crying starting with what you are most comfortable with---for example 3 min., then 5 min., then 8 min. and after that every 8 min. You go in console, pat..kisses...whatever, but don't pick him up until he eventually falls asleep. You can increase the intervals over the next few days to 5 min, 10 min. then 15 min. Since he's sick I didn't want to start that right now, but I was planning on doing it when he gets better. She said he certainly doesn't need to be nursing that much at night b/c he simply doesn't need it, he just wants it. Also I need to work on putting him to bed drowsy rather than fast asleep after nursing. All of these things I know---but its just really hard! She also mentioned adding some more solid foods during the day. I was just doing rice cereal and prunes at night, but she said I could add a morning and noon feeding with some more veggies. Last night I introduced peas and totally expected a funny face, but instead he just opened his mouth up wide for another bite! He loved them! As a result of the peas....he slept from 10:30-4:30 and then went back down from 4:30-8!!!!!!!!!!!!!!! Is it b/c of the peas??? I don't know, but everyone knock on wood...now.
