If kids pulled your nipples, first, firmly but gently tell them that it's not okay. It could be that they don't understand boundaries. You can also try to distract them with a toy or another activity.
I'm not familiar with this exact expression. It could be a misspelling and they meant 'train'. If so, it's still very unclear what it means for guys to 'pull a train' on someone's wife. It might be some sort of inside joke or a very local and unusual way of saying they did something to her related to a train.
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.
I'm not sure specifically what this story is about as the description is very brief. It could potentially be about some sort of prank or accident where some guys are involved in an action related to a train and your wife. Without more details, it's hard to say for sure.
The size of your daughter's nipples could be influenced by multiple things. Firstly, ethnic background can play a role. Different ethnic groups may have different average nipple sizes. Secondly, physical activity levels during development might have an impact. If she was more active in sports or other physical activities, it could have affected the growth and development of her breast tissue and nipples in some way. But in most cases, as long as she is healthy and there are no associated symptoms, it's just a normal variation.

In general, 'My Story Animated' is kid-friendly. It has simple and engaging storylines, colorful animations, and doesn't contain anything too complex or inappropriate for children.
To ensure normal development, it's crucial to have open communication. Let your daughter know that it's normal for bodies to be different. Provide her with proper education about her body, including puberty and breast health. In terms of physical health, make sure she wears well - fitting bras. Bras that are too tight or too loose can potentially affect the development of the breast area, including the nipples. Additionally, schedule regular check - ups with a pediatrician or a gynecologist as she grows up.
