Ok, now you have found out what the name ATL means, you need to ask yourself, is it truly the best name for your baby? Deciding on a first name for your infant is possibly the most important thing you ever do for them, and you could spend weeks, or perhaps all the time leading up to the actual birth, considering whether ATL is the most appropriate name to give your little cherub. As this page shows, ATL is Nahuatl in origin, and so you should consider whether this Nahuatl first name is sensible for your newborn - if you are especially close to Nahuatl culture, then deciding on a unique Nahuatl name for your newborn is most likely acceptable. If this is not the case, then you should consider the possible problems caused by presenting your child with a first name that is alien to your own culture and may lead to peer problems in kindergarten, school and even later in their life. Choosing a unique Nahuatl name for your child may enhance their life, or make it worse - so if you are not 100% sure, then picking a popular name for your infant could be a far better choice in the long run.
