In general, you can expect that the average baby should be able to hold its head up without added support when it reaches the age of 6 months. This is when you can put the baby in the stroller without the added support and cradling of the car seat or bassinet.
When can a baby be in a stroller without the car seat?
So, when can your baby sit in a stroller? For most, it will be from about 3 months old, or when they can support their own head.
When can you put baby in front facing stroller?
And while there are numerous benefits to having a stroller where your baby faces you, when your little guy's development starts changing between 6-9 months, he'll become more interested in what's happening around him. At this point, you'll want to start having him face forward in a stroller.
