Since then some children have not left him alone. They say mean things to him, they laugh at him, I even saw one of them covering his nose when my son came near. It breaks my heart because I notice he is different… he doesn’t want to go to daycare anymore, last night he cried before going to sleep saying that he doesn’t want anyone else to laugh at him
I totally get this, mama. My son went through something similar when he was around 3. He had a potty accident at daycare, and some kids kept teasing him about it. It crushed me to see how much it affected him. He didn’t want to go back, would cry every morning, and his confidence took a huge hit. What helped us was role, playing different responses at home, giving him words to say back, and working closely with the teachers to address it. I also started talking a lot about how accidents happen to everyone, even grown-ups, to help normalize it. It took time, but he eventually got past it and is now a happy, confident kid. Hang in there, this will pass, even if it feels awful right now
Oh, my heart hurts for you and your little guy. My daughter went through something similar when she was 4, she had an accident, and a few kids wouldn’t let it go. She felt so embarrassed, and it took a while to build her back up. What really helped was reminding her that EVERYONE has accidents (even adults, hello childbirth!). I also spoke with her teacher, who made sure to intervene if the teasing continued and helped redirect the kids. Maybe talk to the daycare staff? A gentle conversation with the class about kindness could make a big difference. I know it feels like the end of the world now, but I promise this won’t define him forever. You’re doing a great job just by being there for him
Oh mama, this is so tough, but I promise he will get through it. Little kids don’t always understand how their words hurt, and this might be a chance for the daycare to teach kindness. I bet in a few weeks this will be old news and forgotten by the other kids. If you can, talk to his teacher about addressing it in a way that doesn’t single him out. And keep reminding him that he is amazing just the way he is! This is a hard moment, but it’s just a small part of his story. 
I have an older child who went through something similar, and I remember how painful it was for both of us. First, I’d definitely bring this up with the daycare staff. They need to be aware and step in if needed. Second, at home, I’d focus on building him back up, lots of praise, reminding him that accidents happen to everyone, and maybe reading books about kindness. One thing that worked well for us was practicing some simple, confident responses, like “That was last week, I’m all good now!” It gave my kid something to say if anyone brought it up. Also, consider setting up some playdates with kind kids from his class to help rebuild positive social experiences. It will get better, even if it feels awful right now
I’ve been through this with my older child, and I know how heartbreaking it is. One thing that helped was teaching my kid that sometimes people say unkind things, but it doesn’t define who we are. We talked a lot about how everyone makes mistakes and that real friends won’t judge him for one little accident. I also made sure to casually mention times I had embarrassing moments so he knew it happens to everyone! And don’t underestimate the power of a fun reward, after tough days, we’d do something special together, like making his favorite snack or watching his favorite show. Stay strong, mama, he will bounce back!
