Three weeks ago jamie grumet raised eyebrows across the country breast-feeding her toddler on the cover of "pathways" magazine but it was this "time" magazine photo shoot that had people talking. That boy is like 32 years old. Breast-feeding a child into their toddler years. It's part of something called attachment parenting and it's not without controversy. If you can spell milk, you should not be breast feeding. It's not okay. Grumet heard it all, threats to call social services and accusations of child molestation. I think it's a lot of ignorance so it's hard to get mad at that. She isn't mad but would you be if you heard this? How old is he? 4. He's as big as you are. What you are going to go till he's like 7, 8, 9, 10. I'm traci, I'm going to be playing the instigator. She's the only one we'll use today. The rest of our cast, real mothers who breast-feed their toddlers. Meet her and gibran. Even some need a break. When one is full another one steps in. Our hidden cameras are at sip this in new york with mom and toddler if place, we begin to roll. How old is he? 18 months. 18? Uh-huh. And you're still breast-feeding him? Yeah. I am. Our mom is offended and so is this couple. Can you just -- can you do that in the bathroom or your car? Why would she have to leave? That's ridiculous. Because he's an older kid. That's rude actually. In a show of solidarity, diane gianosis sits right beside our mother and child. I'm just saying if you have a problem with it, take it and leave because she's paying and she has every right -- maybe your mother should have breast fed you. Disgusting. Her husband george has his own take. I don't mind breasts. I'm sorry. Coffee and a breast, what the heck. Little gibran has had his fill so we send in our second mother and child. Don't you think she's a little old for that? Not at all. Not at all. It's the best thing for my kid. I differ. I was breast fed at that age. It didn't affect you psychologically. I'm not psychologically affected right now so it's fine. I'm not allergic to anything. Traci is not convinced. It's disgusting. I'm really s you guys have to look at that. That's your problem and not ours. I think you're making it everybody's problem because you're in public. I'm so sorry. Why are you sorry. Yeah, exactly. He's adorable. Adorable at 21 months but what if it's a 4-year-old being breast fed. We send in danielle and linus. Oh, no. Are you kidding me? He is a big boy. And part of that reason is because he's had breast milk for so long. I think it's because he's growing which means he should eat real food. This is psychological damage to a kid. This is abuse. You're upsetting me and all these other customers. Oh, I need a break. That's ridiculous. I don't -- I wish I would have longer. Can I have a to-go bag for my muffin? But now traci returns to find out she's not the only one who disapproves. It's disgusting, right? These girls decide they don't want to see it either. See, now you're causing people to leave either. Ashley and jacqueline leave the coffee shop and so do we to find out why. Hi, girls. I'm john quinones. How are you doing? Good. How are you? It's uncomfortable situation to see a toddler or a 4-year-old grabbing for breast milk. If a kid is able to go to school they should not be breast fed. Back inside it's still a heated debate. I don't believe in this age right now that you have a problem with that. I just don't. That's why I'm keeping my mouth shut. I don't approve of this. Hopefully you learned something today. Hopefully she does too. Do it at home. If more women would breast-feed in public, the more natural it would become. It's "what would you do?" The tv show. Yes. If the child is 4 years old -- it's okay. To have it at 4 with the mother, it's the best thing. As for danielle, how long will she continue breast-feeding linus? Until, she says, he decides to stop on his own.
