It's not normal at all. Accidental or not, pulling someone's nipples is inappropriate. Kids should be taught from an early age about personal boundaries and respectful behavior towards others. If it happens, it should be addressed right away to prevent it from happening again.
Definitely not. Little kids should be exposed to age - appropriate content like children's books, educational cartoons. Sexual stories are not suitable for their innocent minds and can cause harm in terms of their values formation and psychological well - being.
Sure. Here is one. There was a little kid named Tom. One day, he found a lost puppy in the park. Tom was very kind, so he took the puppy to the nearest pet store. The store owner helped him find the owner of the puppy through the contact information on the puppy's collar. And Tom made a new friend, the puppy's owner.
There are many. For example, some educational cartoons might show kids having a picnic or going to a restaurant to teach about table manners and social skills.
Cartoon kids usually show cleaning activities in a fun and colorful way. They might use big brooms or funny cleaning tools to make it look interesting.
This is completely inappropriate. Nudity is a private matter, and children should be taught to respect privacy from an early age. If your kids show such 'interest', it might be due to a lack of proper education about privacy at home. You should start teaching them about the importance of privacy and appropriate behavior immediately.
