You're a mom so I'll give you the respect and massive props you deserve.
If I were you and you can wait for a month or three, I'd wait until Apple's inevitable "back to school" announcement they have about every year now - there will be an iPhone announcement and possibly other hardware being silently updated. I need a few PCs for my business and have seen a couple of demoed PCs with new hardware in them and they're really nice, but I'm also typing on a 2-year-old rMBP that's capable of driving 2 4k display at the same time - in other words, new stuff may come out but the old stuff works pretty danged well too! The Skylake chip supposedly has 40% faster graphics (and unlike most other MR readers, I've seen that hot chip in action) - but I already can drive 2 4k displays at 60Hz and my "old" SSD launches my Mac in seconds, so I don't see any advantage in the faster chipset for now other than to drive down old tech prices.
The only major changes I'm waiting for are better support for USB 3.1 and TB 3, but they're many months away. Go to a Starbucks - you'll see lots of MacBooks, and maybe a Win laptop. I don't see a significant hardware change in Apple's laptops any time soon. If you need a MB or MBP anytime soon, shop the sales (especially AppleInsider's listing of several other sites for comparison shopping) and Apple's refurb store for better prices. My old Mac works great, but I keep an eye on the shiny new stuff - you can't go wrong now or later, either way!
