Hi M..
first congrats on the babyboy!i remember those days with him! mine is now 5yrs, we are battling the watching cars thing!lol.
lets see, i breast fed, but we started solids as well at 4months. Mind didn't like rice cereal, so we went to 'milky oatmeal cereal'. -it was OK'd by my pedatrician. basically i added 1 tsp of oatmeal cereal to 1-2 oz of whole milk (till i found out he didn't like whole, went to 2% , he was fine then) and widen the hole in the nipple and he ate it fine, but i did WARM it up, he loved it WARM. i also, when it came time, did veggies first, as kids love fruits anyway, the sugar that is naturally in them-they love. you can add a small amount of butter to the green beans, heat it up. if you use the microwave, just stir before giving to the baby, thats why they tell you not to microwave, cause some parents just dish it out, and don't stir, and their are 'hot spots' in there. lol. I didn't know this stuff, as my family was far away, and worked odd hours. my pediatrician probably hated me, but hey, thats what i paid him for! ( i did have military tircare, but went out of the net work to get the best i could for my baby)
my son had some acid reflux, so we had to burp him for 45 min after every feeding. i learned i had like 4 hands! lol.
i was 22, but still, i had no energy! lol. if you are up late at night, give me a IM, i have insomnia, and i am on mountain time! lol.
take care, and congrats!!
