My LO isn't the most adventurous eater. We do expose him to new foods daily that he will hopefully come around to eventually. When he's teething (3 molars currently) he wants nothing to do with solids but will still eat purees. We also keep some packets on hand for walks and outings for quick snacks. At what point should we stop purees entirely? I'm not sure if they're impeding his progress with solids but sometimes I'm happy with whatever gets some calories in him.
