Bienvenue dans l'étape des 4 mois ! À cet âge, votre bébé devient plus curieux du monde qui l'entoure : il sourit davantage, découvre ses mains et commence à babiller. Vous remarquerez peut-être qu'il tient mieux sa tête droite lorsqu'il est sur le ventre et qu'il commence même à se retourner. C'est une étape amusante et pleine de développement rapide. Vous trouverez ci-dessous des informations et des ressources utiles pour accompagner la croissance, le jeu, le sommeil et l'alimentation de votre bébé pendant cette période passionnante.

Concerned About Your Child's Development?
You know your child best. If your baby is not meeting one or more developmental milestones, has lost skills they once had, or if you have any concerns about their development, don’t wait, trust your instincts and seek support.
Start by talking with your child’s healthcare provider. Share your concerns and ask about developmental screening. Early identification and support can make a big difference.
