Quick answers
When do infants roll over?
Many roll front-to-back between 4–6 months; wide normal range exists — tummy time supports development.
When start solid foods?
WHO and AAP recommend around six months when sitting with support and showing interest — not before four months.
Is teething causing fever?
Mild drooling and gum irritation yes; high fever usually has another cause and needs medical review.
When can infants sleep through the night?
Some sleep longer stretches by 6–9 months; many still wake for feeds or comfort — biologically normal.
How important is tummy time?
