Most babies go through several growth spurts during the first 12 months. Common times for growth spurts are during the first few days at home and around 7-10 days, 2-3 weeks, 4-6 weeks, 3 months, 4 months, 6 months and 9 months (more or less). Each is different, so your individual experience may vary.
The Growth Spurts will continue past 9 months and will most likely be noticible every few months during the years as a toddler. The frequencies will decrease as they get older, but they still happen and you will surely notice them when having to buy new clothing they have suddenly grown out of.
What is a growth spurt?
During a growth spurt, breastfed babies nurse more often than usual (This can be as often as often as every hour) and often act grumpier than usual.
The increase in baby’s milk intake during growth spurts is temporary. In exclusively breastfed babies, milk intake increases quickly during the first few weeks of life, then stays about the same between one and six months. As solids are gradually introduced after six months, baby’s milk intake will gradually decrease.
Physical growth is not the only reason that babies may have a temporary need for increased nursing. Babies often exhibit the same type of behavior (increased nursing with or without increased fussiness) when they are working on developmental advances such as rolling over, crawling, walking or talking. Mom’s milk is for growing the brain as well as the body!
How long do growth spurts last?
Growth spurts usually last 2-3 days, but sometimes last a week or so.
What is the best way to handle a growth spurt?
Follow your child’s lead. Baby will automatically get more milk by nursing more frequently, and your milk supply will increase due to the increased nursing. It is not necessary (or advised) to supplement your baby with formula or expressed milk during a growth spurt. Supplementing interferes with the natural supply and demand of milk production and will prevent your body from getting the message to make more milk during the growth spurt.
Some nursing moms feel more hungry or thirsty when baby is going through a growth spurt. Listen to your body — you may need to eat or drink more during the time that baby is nursing more often.
