Hi, This must be baffling! Does your little one like - um - chocolate chips? I used to be a nanny before I had my own kids; I've cared for 5 other babies-to-toddlers for more than a year each. At one point, at about the same age, one girl - Madeline - refused to try new foods anymore. With her older sister's help as an example, "Who wants to try a new food and get chocolate chips?" (your husband could help with the demonstration), we explained a "deal" - one taste of a new food, then one chocolate chip, another taste (can be the same food or a different one), another chip. I can be hard for a little kid to understand simply by explanation, so someone "sitting in" for your son until he gets the idea is a must. Yes, it's a form of bribery, but it worked for me. Once a liked food was discovered, Madeline was happy to just eat some the next time. It became a fun game from time to time, and she eventually stopped refusing to try new foods. If you really cannot abide the idea of sugar bribery, you might try stickers or some other little treat, but in my experiences, sweets are the ultimate motivator.p.s. I'd love feedback on this!
