My pediatrician suggested at 1 year
I just did it at 4 months (before object permanence sets in), but most people don’t wean until 6+ months. Honestly, if I could do it again, I’d wait, because between that, the sleep regression, and having to transfer baby to crib, it has been CRAZY lol. But who knows, it could be harder later! Just depends on the baby’s level of attachment to it I think.
With my first we started around 10 months. We started only using it for sleep and then just slowly stopped offering at nap and then stopped offering at night
My son refusing them since he was about 2 months , I still offer him one and was suggested to stop when they are about a year 2 years max
