Growth Spurt Predictor Calculator

Common growth spurt times are: 1-2 weeks, 3 weeks, 6 weeks, 3 months, 4 months, 6 months, 9 months, 12 months, 18 months, and 24 months. Each baby is different - spurts may happen slightly earlier or later. They typically last 2-7 days.

Key signs include: suddenly increased hunger (wanting to feed much more often), fussiness and irritability, disrupted sleep (waking more at night or napping differently), clinginess, and seeming unsatisfied after normal feeding amounts. These signs usually resolve within a few days.

Yes, feed on demand during growth spurts. For breastfed babies, the increased nursing helps boost your milk supply to match the baby's growing needs. For formula-fed babies, offer additional formula. Do not restrict feeding during a growth spurt. The increased appetite is temporary and necessary.
