Wow .... I had one start at 10 months and was eating jarred food but the jr stuff with the chunks in it, still on a bottle which I had to hold even though the parents claimed she held it herself, and I thought that was a lot of work ... I now have her on a sippy cup and mostly feeding herself, I couldn't imagine pureeing food . I would insist the parent provide the pureed food. Does this child not eat anything that's not pureed? And definately if she is not on the floor and always in an exersaucer of course she doesn't sit or crawl? I provide playpens and highchairs/ boosters if the parents wants something else they would have to provide it. She's pretty demanding I probably would have passed.... But .... I wish you luck
