Desperately looking for mattress pad for my child's crib. She isn't sleeping through the night and I have a strong feeling that her mattress is very uncomfortable.
Take the measurements, and go to any baby store that sells cribs and they should have something (even a proper mattress) to make it more comfortable. We got at chasdei shmuel for our pack n play (it was the mattress that I think goes in the white plastic cribs) and my son sleeps much better. We spent 80 shekels for the size we got.
