Whether it is by crying, whining, or even wiggling, babies are usually good at signaling to parents when they need something — a diaper change, a nap, to be fed. Because they can't talk yet, parents rely on babies' demeanor and body language to tell them what is going on with their little ones. Often, patterns will emerge that help clue parents in on what their baby needs and when they need it. But when a baby's sleep patterns and hunger cues get out of whack, these could be the first signs your baby is going through a growth spurt.
"Babies and children have periods of time where they may experience rapid growth and others where they don’t seem to grow too much. This is normal and expected," Mary Murati, MD, pediatrician at Park Nicollet in St. Louis Park, Minnesota tells Romper.
According to Dr. Murati, growth spurts begin soon after birth and continue into childhood. "Often there is a spurt of growth by about 2 to 3 weeks and again at about 4 to 6 weeks of life. Every few months there may be periods where growth is accelerated, or a 'growth spurt.'"
According to Kelly Mom, babies will experience growth spurts several times during their first year of life and typically last from a few days up to a week long. In addition to the weeks immediately following birth that Dr. Murati mentions, Kelly Mom reported that additional periods of accelerated growth typically happen for babies at 3 months old, 4 months old, 6 months old, and 9 months old. Wow. I'm exhausted just reading that.
