Quoting ☮Sugar Magnolia:" See, I'd have no problem watching my kid's kid every once in a while so they could go hang out with ... [snip!] ... mom does offer to take her every couple weeks for a night so we can have a night out. She's awesome. But, to each their own."
See For a Couple of Hours Every once in a While, if I'm not Babysitting All the Time, sure. That's Different. But If I'm Looking after Baby All Day while they're in school, or All Night while they're working, and especially if I'm Watching Baby for them to Do Both of those things, I will Need a Break from Baby too. My Point is "I'm Not the Mom, I get time Off From YOUR Baby! Same as ANY Childcare Employee". Legally a Nanny Can't Watch Baby for those Kinds of Hours, so a Free Nanny definitely can't! And What about the Other Set of Grandparent's?
My Mom lives with Us, at least for Now. She Babysits(For a Cup of Coffee is our ongoing Joke on "Fee") for Me to go to work, When DH can't, around her Own Work Schedule. She also will look after one or the Other, or even both while I/we go do something (right now usually My Daughter while I take my son to Taekwon Do). Because of Finances Night's Out Kidless are Far & Few between(We're planning a Hobbit night, 'though that may have been Destroyed since DH has been laid off yesterday). I also Call her "The Third Parent", Because she is there, & so involved with their Lives, But no matter how much she looks out/after them, there is No Doubt that She is NOT their Mom! I have to ask her before I make Plans, I can't just say "I'm Gone" & leave the kids, & I can't just go Galloping off for Hours at end with out My kids.
Alot of times with Teen Parents, School, Work & Friends in varying Order are totally put before "Baby". I would Much rather if I have a Child who has their own Baby before they're Old enough to Vote, Join the Military &/or Legally Drink be a Parent than a "Teen Parent". I know people who had their First Kid at 30 who are still "Teen Parent's", & Some who had their First at 15 Second by 17 & They are NOT "Teen Parent's".
