I totally agree Alli, and thats my argument for sweets when people pressure me to give DS some. He won't know what he's missing til someone starts giving it to him! Grrr.
Hugs Moon-dell! DH gave me a bit of a hard time at first when he saw the gagging, but has since come around. Until he did, I just avoided any challenging foods while he was around or if I was around inlaws. What about encouraging your LO to eat from a loaded spoon so you are still following BLW but the food would be soft like cereal, soups, soft fruit or something like that? Or even just offer the different foods at a family meal but smaller pieces? He will still be able to feed himself and try what he likes.
If you can get DH onside you'll find others will interfere less. I feel confident now when DS stuffs a big wad of whatever in his mouth that he can handle it. The first few weeks were fun and awkward at the same time.
