But you could pick an age when you know for sure that it would be ok. I mean, if you wouldn't send your 16 year old, I don't care how immature you felt she was, I would think that was very overprotective. Nobody can "hold you to it". It's not like they can take legal action because you made a promise. You can always change your mind but it would be a nice gesture to at least offer something.
No, I don't think you CAN pick an age when you know anything for sure. My ILs have taken their two DDs and their families on cruises. On one cruise, a bunch of 15 year old girls celebrating one's quinceanera thought 13 yr old nephew was adorable. He called his mother from one girl's room at 3 AM (why he was out and unsupervised at 3 AM, I don't know...but I guess that's the "overprotective parent" in me) to ask if he could stay the rest of the night. My ILs thought how cute that all these girls liked him so much. This was the time she also said to me that cruises are great, because you don't even have to SEE your kids. (Personally, I LIKE "seeing" my kids when we're on a family vacation.

) And that "Oh, MaryAnn, they can't get in trouble on a cruise."

When that particular nephew was about 15 and on another cruise with the family, we heard later how he and one of his cousins got drunk and puked all over their stateroom. A couple of them also jumped off an upper deck into the water, got caught by security and almost thrown off the ship. Now...do I want my ILs, who tell these stories like they're cute adorable funny family stories, in charge of my kids? Nope. At ANY age. At some point, I lose my control over what my kids will do, but I would strongly discourage my kids from vacationing with these people, ever. Not that it would be a big deal...they hardly know each other, because ILs wanted the vacations with the kids, but not want to watch them for a couple of hours here and there while I went to a Dr appt.
And yes, I do think the ILs would attempt to hold someone to a statement that "when she's 15, she can xyz"...it gives them ammunition to fire back when you decide that "15" is NOT the right age, for whatever reason. OBVIOUSLY I don't expect that they would take legal action.
And this is the part that I don't agree with. When did the mother become the more important parent? (OP, I'm not saying that this is how you see yourself. I'm simply responding to some of the assertions to this effect on this thread.) Why is the mother's say more important than the father's say? I don't get that at all. Clearly, this couple is divided and needs to come up with a solution that works for both of them. I don't think it's fair for one parent to have vito power over the other's parenting decisions.
That is really the only problem I have with the OP's situation as she has explained it. I can honestly understand where she is coming from but I can understand where her DH is coming from also.
And if there IS no solution that works for both of them? Of course, I'm sure you and your boyfriend will always come to the perfect solution.
Do you have children? I am guessing no. I'm not trying to be rude but
everyone has their perfect theories about raising a child until said child is actually here. Then all that flies out the window.
Sure, 50/50 is wonderful, but that isn't always possible. I also don't think that not allowing you 11 year old to fly to someone's home that would make her sick is being overprotective. It is being smart.
You can have an opinion. I am not saying you can't. However what you see with the people you know is only a small snippet of what actually goes on behind closed doors.
I don't believe that ANY relationship is literally 50/50. My DH and I are on the same page the majority of the time when it comes to child rearing, and always have been. And boy, am I grateful for that! But in every aspect of our relationship, there's
some imbalance...someone's contribution is a little more, or carries more weight. We don't sit down and do everything together, like pay the bills, or make purchases of all sizes. I'm a SAHM...my decisions
usually carry more weight. Like I said...we're very much on the same page with child-rearing. But, if I
very strongly feel a certain way...if I'm downright adamant about it...and DH feels less strongly, then what I say goes. That doesn't mean I've never allowed my kids to do something that I'm less than totally comfortable with, or that I wouldn't say "I'm not thrilled about it, but...OK." My long-winded point is this...50/50 is more theory than reality.
