It is not entirely clear from your description what exactly the nature or cause of the bump on the tip of your daughter's tongue is. It would probably be best if you showed it to your family doctor. One would need to examine the bump to determine exactly what it is.
However, that said, I can give you a few possibilities and options for home treatment. Herpes is extremely unlikely. What is most likely is that these are benign fibromas —growths that often result from minor local injuries, such as biting your tongue. Try to make note of whether these bumps follow such an injury. Another possibility, although unlikely, is what is known as lie bumps. These are painful papillae on the tongue. Not much is known about the cause of lie bumps, but they are often thought to be caused by irritation of the taste buds by teeth or rough/sharp textured food. There is no real known treatment for lie bumps. The only option is to ease the pain by using ice or a numbing oral gel or solution. Gargling with salt water is also supposed to help. Still, as mentioned earlier, you should visit your family doctor for an examination.
