Graco - Nautilus SnugLock Grow 3-in-1 Forward-Facing Harness Booster Car Seat

We have the Grayco Nautilis and it's very easy to strap in and out. I also found that the one you have was really hard to get tight and install. The Nautilus is really lightweight too, so it's easy to switch.

We’ve loved our Graco grow with me 3in1 (or something like that). It is pricey though. I don’t know much anything about it but Sam’s club has the safety 1st car seat for $99 every time I look.

For the diaper bag I just got a cooler back pack haha. It’s big enough that it fits everything I need especially for 2+ kids. It’s been very durable. Stroller it depends on your needs. I just got a travel system on sale. Car seat I got a Graco that grows with the kid. The one that I picked didn’t weigh much so that was a plus. For car we got a mini van and I love it! It’s so spacious and it’s so easy to put the kids on there without much struggle. Especially when space is limited (cars are parked next us). I think it’s good if you’re planning on having more than 1 kid. But even with one I still would’ve bought it.
