A.B.
You remind me a lot of me when my son was that age. I worried a lot about when and what to give our son just like you are now! If I gave him enough, if he was malnurished if he skipped a meal or wasnt interested in something I was offering.. And the real truth was he was a healthy, well fed hunk-a-chunk! Honestly, I think they best thing you can do is be knowledgable of foods and their qualities and just be in tune with your little one. There is so much "taboo" stuff now of what to do and what not to do that it really bogs you down as a parent. Go with your gut instinct, when we were growing up our parents didn't have any knowledge of what they know now and we survived! My son is about to be 1 year now and he LOVES his people food!! I started introducing him to baby food about the same time that you are. He really enjoyed the different tastes. We watched for any rashes or if he was experiencing any digestive problems and either backed off certain foods for a while or would feed him things like prunes to help. We don't have any allergies in either side of our family so I didn't feel so worried that he would be. Certain foods like eggs are too complex for babys until they're older. He loves them now! Or tomatos have lots of acid and can cause a rash around the mouth area (baby skin is so sensitive!) Bananas are great food starters but make sure not to give too much, just like cheese they can cause constipation! I started with fruits worried that he wouldnt like veggies as much and he lucky for us he just plain loves all food! Just as soon as our son was onto baby food, we started giving him bites of our food, which he immediately was turned onto because the food actually had taste and texture!! Our son also had 4 teeth come in at 4-5months and had a total of 8 teeth at 8 months so how could we not? What better of "My body is ready for solid food" indication was that? It got my husband and I eating better healthier meals and all at the same time.
As for your little one, as long as he is drinking plenty of milk and able to support himself in a good eating position (can sit up in high chair/swing with good head support) then he is ready to taste some new stuff! Since he doesn't need it for his nutrition I wouldn't worry too much about how much to give him or making it a point to do it as an everyday activity, as long as he's getting plenty of milk thats all he needs! But you could make it like a fun snack or dinner meal time participation, when time permits. I remember how fun it was to provide those new experiences and he'll enjoy them too!! Hope this helps?!
