Hi... May I know how many months is your baby? Parents can safely start using pillows for children who are 1½ years old, about the same age at which parents can safely move children out of the crib and either into a toddler bed or onto a mattress on the floor.
If your baby is sleeping in the cot, try to put some blankets or pillow under the mattress and make it slanted, instead of letting LO sleep in the pillow. My girl was a colic and reflux baby, this is what we did, recommended by PD.
Don’t mentioned, hope it works for your baby :)
Small babies and young children do not really need a pillow. Flat surface on bed will do. Place a cloth or napkin beneath the head.
Instead of pillows, try to pop up the mattress. You may put some towels underneath. Not too high else baby might slide down
I use this kind .. from newborn till he can fit.
How old is your baby?
