## Questions & Answers

**Q: Do these help with diaper blowouts? My daughter likes to poop in the middle of the night and it’s going through her pj’s and sleep sack!**
A: They help my daughter mostly with urine leaks since the Sposie absorbs liquid. She does poop in the morning and has not had a blow out with one of these in her diaper. 

I think the Sposie may help if the diaper is overloaded and then she poops. If not, maybe try sizing up a diaper :)

**Q: Are the diapers biodegradable? If so, what percentage? I hate thinking that each diaper will last hundreds of years in some trash pile.**
A: These aren’t diapers. They are inserts you add to diapers that add extra absorbency. That being said, they seem like they are made of the same materials as regular diapers, so I doubt if they are biodegradable.

**Q: Could these be used during wake times as well? My baby is having regular leaks but not ready to go to the next diaper size.**
A: These honestly made the leaking situation worse for us. I swear the pee just rolls off these pads instead of absorbing in. Try a different brand during the in-between size times. Huggies run a little smaller than pampers swaddlers.

**Q: My son can wear a 3 & 4 diaper would these be too small? Im worried the 4-6 size would be too big!**
A: My daughter wears a 3 & 4 diaper and I purchased the size N-3. They have worked great and haven’t had any leaks when I put one in her diaper over night! They aren’t too small. They give a great amount of extra absorption!
