Solid foods?

To start solid foods, or delay starting solid foods, that is the question! Even with the go ahead from our pediatrician, I'm just unsure of starting Caleb on solids, even just cereal, already. And to google the issue brings about so much information that it has been challenging to sift through and gather opinions, deciding the pros and cons of it all. It seems the biggest push is to wait til 6 months and then to be sure that solids are in addition to breastmilk, not replacing it as part of his diet. I think this is what we are leaning toward, since most of the opinions/research studies reflect it being better for a child's digestive tract in development to wait until closer to 6 months. Since we know that Caleb has a very sensitive system (what with the dairy allergy and reaction to spicy food and red sauces) it seems it would be smarter to wait a little bit longer. I guess it all just makes me nervous- even though feedings have been rough with him, it's fairly simple as he is only suppose to be getting breastmilk. Now that we are entering this next phase, the decision making really starts for our son and it is a little scary. I know it's just food, but it seems like the reality of the decisions that lie ahead in terms of food (developing good eating habits), exercise, entertainment, discipline, schooling, dating, etc. are all coming at us! I know, I know, take it easy Bev! He's only 4 months! But, it's good to think on what's next so it doesn't blindside us like I feel the introduction of solids has done. Anyways, I hope whatever it is we decide on, it will be honored and respected by family and friends.
