So you just had a kid and live in Fl, is it safe to assume you won't be doing any tech diving for a while? In keeping with your original post, here's a couple other options.
First of all the Litehawk mentioned in the previous post is the 2013 model but there's a new, not discontinued model sold by Scubapro Dealers (not LP apparently) for $414. It doesn't have the insane amount of lift the earlier model does - I have a 65 lb.
doubles wing...lol. You can probably find it locally but here's one Platinum Reseller's link -

IMO a Seahawk is marketed somewhat to dive professionals who need to carry a lot of stuff on dives - hence the big pockets. I liked the Knighthawk but bought a Ranger instead, it does have a problem with the pockets tightening up once there's a tank/weight installed but only on the surface - once in the water they're fine. At the time my diving was mostly SoCal (cold) and I assumed twins - I don't do either now.
I also briefly owned a Stiletto, bought thinking it would fold small enough for a carryon - which it did if I didn't bring anything else. So I returned it b4 getting it wet.
In your situation I'd look hard at an Express Tech, it's their soft backplate minimalist design that you configure as needed. It comes with either a 24 or 35lb. wing, you can add either of their weight systems and besides their expensive pockets, DGX sells some that will also work. They're $385, $100 more with the ZipTouch weight system.

Maybe a Covert also but they're less configurable but better for travel due to being under 4 lbs. May not be as important in your situation currently but it's an option - 32lbs. lift with a weight system for $453. I may buy one eventually.

A problem with the high-lift models like the 2013 Lighthawk or the Hollis is unless you're pulling up anchors, the wing creates un-needed drag in normal use.
hth, my Zeagle has seen the inside of a shop once this decade and that was only because the first service was included. I've changed inflators once to swap to their BX model which makes it easy to flush (with a garden hose). $60 plus two cable ties has been my total investment.
