Babies get shaken most after periods of inconsolable crying. Since April is Child Abuse Prevention month, here’s some information on abusive head trauma (previously know as “shaken baby syndrome”) and ways you can help support new parents with babies who cry.
All babies cry. But some babies cry more (see the graph in the video). Babies do follow predictable patterns in crying: most babies start crying around 2 weeks of age and their crying peaks by 2 months, then tends to resolve around 3 to 4 months of age. But there are some babies who simply cry more than others. Dr Ronald Barr has researched crying in infants for over 30 years and developed the PURPLE period of crying based off data on all types of infants. Learning about the PURPLE period so you can help reassure families that they aren’t doing ANYTHING WRONG when they have a fussy baby. It’s okay that a baby fusses and cries, particularly at peak times (around 2 months of age, in the evening), our job as parents and community members is to support parents dealing with this fussiness.
Crying is aggravating to all of us. When I spoke with Dr Ken Feldman, a pediatrician and expert in shaken baby syndrome (now called abusive head trauma), he reminded me of a startling finding. He mentioned a North Carolina study found that 20% of parents surveyed admitted to shaking a baby out of frustration at some point.
You’re not alone if you’ve felt overwhelmed while caring for a cranky baby.
Take turns soothing fussy babies. Put babies in their cribs on their backs if you get really frustrated. It’s always okay to walk away from a really cranky baby for a 10-15 minute break!

Often new parents are nervous about mixing and matching infant formula they offer their babies. They worry if they switch from one formula brand to another, they may cause their baby fussiness, stool changes, upset or worse–that they could put their baby at risk.
The 2 month-old check up may be harder for parents than it is for babies. Getting the first set of shots is anxiety provoking for we moms and dads; no question that it’s unsettling to allow a medical provider to cause our beautiful, new, healthy baby pain. Research has found that the pain and discomfort associated with shots is one of the primary reasons parents “elect not to perform timely vaccination.”
