I discovered a trick for car seat installation and I couldn't keep it to myself :). When I use LATCH installation, it seemed like no matter what I did I could never get the car seat/base tightened down enough for the '1 inch' rule. Buuut, if you own a crossover/SUV/minivan there's a trick to get it tighter. Recline the seat you're installing the car seat on just a little, tighten the LATCH straps as normal and then bring the seat back up to normal position. Instantly tighter with no struggle! It's made my life easier, and I hope it helps you, too!
