Chances are that he is going through a baby growth spurt. During a growth spurt, your baby's height, weight and brain will grow rapidly; this is a brief phase during which your baby will grow very quickly. These bursts are all natural and they are considered a landmark in the maturity process of your baby.

When Do Babies Have Growth Spurts?

A baby will experience a number of periods of growth during the first months/first year The spurts may be dramatic and are likely to be between a number of days up to a week. The growth spurts most usually occur at:

Around 7–10 days
At 2–3 weeks
At 4–6 weeks
At 3 months
At 6 months
Around 9 months

Growth is not simultaneous in all babies and hence some can take a growth spurt ahead of others. In general, however, these are the usual milestones wherein the parents notice abrupt changes in eating habits, sleep patterns as well as behavior.

Good sleep: Do not allow your baby to sleep less when they look tired.
Keep calm: This stage is only temporary and necessary to develop.

Tummy time: Helps in enhancing physical growth and motor skills.
Play and talk time: This will enhance brain development as well as bonding.
Check-ups: Aid in monitoring development and detecting issues before they progress.

Growth Spurts vs. Other Developmental Changes

Not every change means a growth spurt. Here’s how to tell the difference:

Growth Spurt	Developmental Leap
Sudden increased feeding and fussiness	New skills like rolling or babbling
Lasts a few days	Lasts 1–2 weeks
Physical changes more visible	Cognitive and emotional changes more likely
Baby may sleep more or less	Baby might resist sleep or show frustration

Tip: Both are normal and often happen together. Keep observing patterns and trust your instincts.

Sleep when baby sleeps

There is nothing you can give when you have nothing to give. Caring about you = welfare of your baby.
