My LB used it right up until he was about 1 and a half and he stopped liking it and preferred lullabies! Hes 3.5 and still using lullabies to sleep
My 2 year old still has white noise or lullabies on overnight
My 2 year old still had white noise at night!
Every baby is different - you know your baby best and what they need 💕
