Is it safe to give a 6 month old fruit?

Yes, it's o.k. to give a 6 month old fruit. I would try a new food every 2-3 days at that age. It's totally up to you how many times a day you want to feed her. I started feeding solids at 6 mos. I started with one feeding a day and moved up from there when each successive feeding was going well. He's 9 mos. now and is eating solids 3 times a day. At 6 mos. I was giving fruit in a pureed form. I did use the mesh feeder, but I don't think he really got much out if it.
