Helmet baby’s

Kr

Any mommas on here have LOs who have had to wear a helmet to reshape their flattened head? My daughter had a sack of fluid on the left side of her head after delivery and due to this her head has had a rough time shaping the right way. Doctor is giving LO another month and bunches of tummy time to hopefully see some improvement before taking further action. Just looking for a little advice and other mommas stories of their own LOs and their helmet. I’m simply trying to prepare myself for the possible future.
