How Long will babies outgrow baby cot, bouncer? At what age do you still carry ur Bubs in a carrier/ sling?

Hi, Well! It depends on the size and weight of the baby but generally the baby outgrows baby cot in 15 months or so. My baby cot was designed in way that it would not tip off so my baby used to get out of it and go on her own by the time she turned a little more than one year. I carried my baby in sling till 7 months. She turned heavier and I had to shift her to a pram and stroller.
