I was going to bump this over to the solids board thinking you might get more input there, but then I saw your edit! You might want to check out the FAQ on "Is your baby ready":
https://babywhispererforums.com/index.php?topic=36922.0FYI, most health organizations recommend bf'ing for the first 6 months, and only starting solids after that. There are a number of health benefits to doing so, few for starting solids much earlier, and some potential risks if you're baby is not ready.
Babies tend to be very curious at this age, but it doesn't necessarily mean they're ready! They also reach for the TV remote and dirt!

I personally waited until 6 months for both my kids - I wanted to give them the full benefits of 6 months of just bf before adding anything else to their tummies....but it IS a very individual decision.
