My daughter is 5 1/2 yrs and was struggling w staying asleep the entire nite. She inevitably always ended up in our bed in the middle of the nite. The first nite she slept w the sleep zzz pillow she slept through the nite. She said she loved how soft it was and felt so cozy and snuggled up! She hasn’t come in to our room all the following nites– now we are all sleeping through the nite!! Highly recommend!!
