Between birth and two years of age, your baby will develop at an extraordinary speed, and each of their advancements will be a new source of wonder for you. Discover with us the major milestones in their development and how to interact with them to help stimulate their awakening.
Your pregnancy started exactly one year ago... Three months of age marks an important transition for your little one: they are no longer a newborn but a baby who is starting to open up to the world around them. Discover with us their amazing progress, without worrying if they haven't yet reached all the indicated milestones: even though there are some benchmarks, every child develops at their own pace!
Their weight and height
Your baby is growing at lightning speed: on average, at 3 months, little boys weigh 5.8 kg and are 60 cm tall, and little girls weigh 5.3 kg and are 59 cm tall.
Their gross motor skills
Your baby is now able to hold their head up straight when you carry them, but it still tends to fall back after a few moments. If you lay them on their stomach, they will lift their head and support themselves on their forearms for a short period. On their back, they extend and flex their legs in turn: they love to kick their legs in the air!
Their fine motor skills
Involuntary at birth, your baby's movements and gestures become more precise and controlled. At rest, their hands are no longer clenched but almost open: fascinated by their movements, they spend a lot of time contemplating them. If you present them with a toy, they are able to grasp it and then drop it after a few moments. They start trying to grab the abacus or small toys hanging from the arch of their bouncer or stroller.
Their awakening
Very sociable, your baby smiles at everyone and accepts being held even by those they don't know. However, their preference is clearly for the people they live with every day: their dad, mom, siblings, their nanny... They show their joy when they see you arrive and follow you with their eyes when you move around them. They begin to take an interest in the world around them and greatly enjoy walks in a baby carrier or stroller.
Your baby communicates more and more too: from 2 months, cooing appears. Giggles, coos, throat sounds, vocalizations and little cries of joy... They play with the capacities of their larynx and their adorable babbling is simply irresistible!
Their sleep
During the day, your baby now has long periods of wakefulness and their naps are starting to become more regular. At night, their sleep also stabilizes: at 3 months, many babies sleep 6 to 8 hours straight, and so it can be considered that they are sleeping through the night... even if they may seem very short to you!
However, if your child still wakes up one or more times a night, don't worry: there's nothing abnormal about it. You can continue to feed them at night: this will reassure them, without delaying the appearance of long nights of uninterrupted sleep.
