My 5month old has been eating solids since 17weeks and loves mostly everything. I want to try some different fruits other than apple or pear and apple and pear mixed together. Ive tried nectarine and also apricot but I found them way too tart and didn't want to add sugar! Is there anyone out there that knows any good combos or should I stick with what I know?? Thanks :)
