If you have an average-size baby, you can expect her to double her birth weight by five months of age, triple it by one year, and quadruple it by two years.
- The average gain in length or height is 25 cm in the first year.
- These average estimates could be different if your baby was premature, is naturally small or has been ill.
- 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). It will vary with every baby.
- 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. A 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 or sticking to a fixed schedule of feeds interferes with the natural supply and demand of milk production, and will prevent your body from getting the message to make more milk.
- 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.
- Your baby will probably sleep more during the growth spurt, and you should also, as the extra milk production can be tiring.
