Introducing Rice Cereal...
It's an Old Wives' Tale that putting Rice Cereal into a baby's bottle right before bed will help them sleep longer. Women have been doing it for generations, despite the fact that a lot of people (including some doctors!) advise against it.
The American Board of Pediatrics recommends that infants are exclusively fed formula or breast milk for at least 4 months, but preferably up to 6 months. The ABP suggests solid foods, such as grains, fruits and vegetables can be introduced at six months, though many pediatricians advocate introducing them at as early as four months.
At around 3 months, Clinton and I started giving Lucas rice cereal in a bottle, mixed in his breast milk right before bed. We noticed that no matter how much breast milk he was drinking (whether from a bottle or the breast), he just didn't seem to remain full for any length of time at night.
Introducing Fruits and Veggies...
At Lucas' 4-month check-up, our family doctor told us that we could begin giving him pureed fruits and veggies, as long as we were comfortable doing so. Since Lucas was already receiving Rice Cereal, Dr. Youngs recommended that we try some fruits and veggies. Sweet Potatoes, Squash, and Green Beans were his first suggestions.
I heard from a friend that it is good practice to give your baby a large variety of vegetables before introducing fruits, and our Doctor confirmed this fact. Because fruits are so sweet and yummy, most babies refuse veggies, if given the option between the two.
I used this method with Lucas, and to this day, he favors veggies over most fruits. Granted, he does show preference toward certain vegetables, but is an all-around good eater.
