Cell phones do not have a big learning curve. Think about when you got your first cell phone. It probably did not take long for you to master it. There is starting to be a push for people to wait until their kids are in 8th grade before giving their kids cell phones. I wish I had waited until mine were in 8th grade. Treasure the time you have with your kids while they do not constantly have a cell phone in their hand. I have no doubt they will be better adjusted without the distraction of a phone if you wait until 8th grade. Stay strong.
