Baby Milestones: Rolling Over

Just like any milestone, when a child should reach it is an estimate. According to the American Academy of Pediatrics Milestones, most infants will start rolling from tummy to back around 2-3 months. This is an easier task since they are able to use their arms  and the weight of their body to push/pull themselves over.
When it comes to turning from back to belly, this proves to be a harder process since their abdomen and back muscles have to do a lot of the work. Most babies won't roll back to belly until 5-6 months, but should be able to roll either front to back or back to front by seven months (http://www.aap.org/publiced/BK0_DevMile_7Mos.htm).
There are those babies who go from not moving straight to scooting and/or crawling, Each child is different on their milestone timeline, but understand when the child does start moving around in their crib, decorative bumper pads need to be removed. Although these are usually part of the linen bed-in-a-bag kits that are sold everywhere, they can be dangerous for babies who snuggle up next to the soft
pads and mash their faces into them.
As any parent, it is normal to worry about a child's "normal" developmental process, but understand that reading numerous websites and listening to people tell you something could be wrong will only drive a parent to this side of panic.
If there are any worries or concerns on when your child should be turning over and back or meeting any of their milestones, consult your health care practitioner. Never feel as though the pediatrician or family practitioner won't be receptive to a parent's concerns.
There is never any harm in asking and it can help you better understand your babies development.
