Fantastic SIO
Oct 10, 2025
If you don't feel like using a two-piece diaper (on the go, for example), this one is really great. Absorbs relatively a lot. My child is 8 pounds and the booster doesn't even need to be on yet, so really a thin package. Even used it once in an emergency at night and no leaks then either, but I wouldn't rely on that ;)
Good absorption and easy to put on

Fits a lot of pants. Only bii the one size from bare and boho I can't get him to fit nicely under them. We usually use prefold diapers, but these inserts when he has to use a diaper a little longer due to outings. And he goes with us to babysitters clicked into an overpants, so they can easily put a washable diaper on too.
Very nice

We use them in combination with different overpants (elskbar, bare and boho, lighthouse sio, sometimes loose in totsbots or blumchen pants under the flaps). I like them best of the inserts we have. Are nice and soft, absorb a lot. Son is now over 4 months and don't need the booster yet, the insert lasts easily 3h. Also dries quickly because you can click 2 layers apart. Soft edge at the legs which also helps to catch poop, therefore less frequent dirty pants with these than with other sio inserts. I also think the advantage of the sio system is that it is not a very thick package on a little one, if you compare it to pre-shaped diaper and pants.
We now use the booster from this set in the pocket of kekoa diapers, and then the trifold that goes with it on top. That actually works really well too, because the actual insert from kekoa doesn't fit in the diaper right now, still adjusted small.
Good product, highly recommended

I am extremely pleased with these inserts! At the beginning I thought wow so little fabric, but it absorbs super. at night I put a 2nd booster from another set on and it pulls for 12 hours without leaks. Top! (Baby is now 4 months).
I had the idea beforehand that because of the elastic in the legs, the insert would hold everything back well. But with a big load of liquid bv poop, the insert has some trouble. That's why I started using hydrophilic wipes during the day. They absorb a little faster so the poop stays on the pad more often. It is now a bit 50/50 whether it stays on or not.
Other big plus is that they dry super fast! You snap them completely apart and with 2 days they are dry in the closet. I also wash every other day now so I'm fine.
Lastly, this system is more economical than a pre-shaped diaper, which really attracted me.
Fine sio inserts

I use these icm overpants from petit lulu itself, elskbar and buttons super. I use them now without the included booster and can do 3 hours with them. It is a nice slim package. However, without booster there is a press stud that sticks out at the top and pokes into my son, which I find less convenient. So I fold an insert (which I use anyway) double against it so it can't hurt him. Because you can unclip them, they dry really quickly.
