Children do not need cell phones or Facebook pages. They need parents who recognize that they are children, not mini-adults. Sorry to be so blunt, but I'm sick and tired of seeing friends who let their young kids have FB pages and then seeing them post things like I'm looking for a relationship or I'm in a relationship. I'm sick of seeing kids not even being able to interact with each other or other human beings because all they know how to do is text. I'm sick and tired of seeing 11 year old girls in full face make-up and carrying a more expensive handbag than their mothers do.
My kids are 8, 9, 10 and 13 and none of them have an email account, a cell phone or a Facebook account and I'm going to keep it that way for as long as possible.
Well I am glad that works for you and i would never presume to tell an other parent that her child should have a cell phone/email address/facebook page whatever. Plenty of family situations do not require, or want such things and that is awesome for them (really, I have no issue with that at all). I found your post to be condescending and rude in the way you express being '"sick and tired" of people making different parenting choices than you (choices which in no way affect you).
I actually think it is fine to have any of these things "just because" (except facebook under 13 only becuase it is their ruls and I believe they have the right to make rules and have them followed--but I think there are as many problems with adults on facebook as teens--though I can't really say, my DD13 refuses to open a facebook account SHE does not like it because she wants to keep in touch with just her friends and not see all of their comments to their friends pop up on their walls

) I truly wish MY DD would open a Facebook account so she could keep in contact that way too--DS wants one and will likely have it set up before breakfast on his 13th birthday
Maybe my kids don't NEED email--but it sure as heck has helped them with moving to a foreign country. They had just turned 10 and 12 when we moved. 12 is a hard age for girls anyway, moving to a foriegn country and starting over in a new school where you do not even speak the langauge at that age is majorly stressful. I am thankful that DD and her little brother can stay in contact with their old friends via email. It is a good thing their friends' parents do not have your views. That contact with old friends has been a life saver on some stressful days.
Cell phones? Well, hey, it's great that you can always be with your kids. I wish I had that option. Life does not always work that way for all of us. MY kids take a train and a street car (plus walking or biking) to get to/from school. We really do not have much choice. Here it is totally common to let kids go home early--(with no warning to parents) if a teacher is sick, Germany has an afternoon game in the world cup, etc. So, even if I had all the time in the world to go and pick them up every day I would not know when to go. Also, one is often done an hour or two before the other and I could not get back and forth to pick one up, return them home and then pick up the other in time. Should I just sit outside the school all day every day waiting for them? Make whoeever gets out first wait on the other (DS11 gets out 2 hours early twice a week and DD13 once a week--all on different days)? It is just not realistic. SO, I do what I think is the safest thing--I give them both cell phones and they always call me when they leave school so I know when to expect them. This also means DD13 can go to the library or shopping with friends once in a while and DS11 can call me for advice (and to let me know he will be late) when a train with mechanical problems returns to the station or some other unexpected ting happens. For me the cell phones are part of how I am (in your words) "doing everything I can to protect my kids for as long as I can."
Neither DD nor I carry expensive purses--it is not our thing. But she has a kindle--that's pricey. Other kids have DSs or really pricey
Lego sets or whatever. Everyone has something they love. If you do not give into a child's every whim and spoil them rotten what is wrong with giving them something they truly want if you can afford to do so
And make-up. I do not care for the overly made up look myself and DD is self proclaimed "too lazy to get up in time for make-up" but so what. Does this tell you anything about the kid other than perhaps no one has taught her how to apply make-up well? Do you always judge so quickly based only on looks?
Really, you raise your kids in the way that works for your situation and trust that the rest of us are doing the same please.
