Do you have a set time for how long they have to eat or a set amount? I have a little boy that could eat for atleast two hours straight. I've talked to his mom about it and she says just leave him in the chair till he's done. I tested it one rainy day and just stopped after the two hours cause it was getting close to lunch time. I think she does this at home all the time. He's a big boy. He's not even a year and a half. He's bigger the my almost 5 year old. He's almost 40 pounds. Any thoughts? I don't like leaving a child hungry but we have activities planned and only am hour between lunch and nap time. Ugh
