Yup! Sort of trial-and-error with my preferences. Here's what I've tried:
Sposies - don't like them, too small. Was told to try doubling them, haven't tried that yet.
Abu Power-Ups (US) - mid-range booster that's on the pricier end. They absorb well but they're the only booster I've had "explode" SAP gel inside the diaper. Pass from me.
Rearz overnight booster pads - I WANT to love these....they're super bulky and soft, and make any diaper feel instantly thick. Problem is, they don't absorb quick enough for me or my partner (and we have different anatomy) and both have caused our dry diapers to leak completely out of the sides. No way we can use them.
InControl booster - bought these for a cheaper option - they're OK. Don't absorb as much as other boosters, but much better than the small sposies. An economical choice that adds a nice additional absorbency to any diaper. Kind of scratchy material to the touch, but no issues when in use.
NorthShore EternaDry L - my FAVORITE booster by far. Expensive? Yes, but quality is top notch. Holds a ton, distributes well, swells up nice, and is the perfect dimensions to slap into any diaper. I've been holding onto my last pack and slowly going through them because I enjoy them so much. Definitely my go-to.
I know there's lots more options out there, these are just my experiences with what I've tried. Test things out, see what works best for you and go from there. Hope this helps!
