Hey there, amazing parent!
Welcome to Month 4! A time when your baby is starting to move, wiggle, and discover the world in exciting new ways.
You might notice more kicks, more stretches, and more of those curious little looks that seem to say, “What’s that? What’s next?”
There may be a little more rhythm now and hopefully a little more sleep! It’s amazing how it quietly arrives. I always forget how the madness does ease (even with my second and third) One day you just notice your shoulders drop and think, oh… we’re okay. (Even if its just for a little while) 💛
Activity 1: 🗣️ Baby Conversations
How:
Hold your baby so they can clearly see your face. Smile, chat, and wait for them to make a sound, coo, smile, or move. When they do, respond as if you're having a real conversation—copy their sounds, answer with your own words, and then pause to give them another turn. Keep the interaction relaxed and follow your baby's lead.
Why: These back-and-forth interactions, known as serve and return, help your baby learn that communication is a two-way process. They build strong brain connections, support language development, strengthen your bond, and help your baby feel heard, valued, and connected from the very beginning.
Activity 2: Mirror Play
How: Place your baby in front of a baby-safe mirror and let them observe themselves. You can also join in; make faces, smile, or wave.
There are some great fold out tummy time mirrors, or hold them in front of the bathroom mirror, sit/ lay together in front of wardrobe mirrors or just hold up a little hand held mirror with baby on your lap (they will probably grab at it and try and eat it, which is ok too).
Why: Mirror play helps develop visual awareness and brain–body connection. Babies love watching moving things, and their brain is wiring attention, focus, and self-recognition.
Nursery Rhyme: Row, Row, Row Your Boat
This gentle, repetitive song is perfect for rocking, bouncing, or moving your baby in a safe rhythm.
Row, Row, Row your boat,
Gently down the stream,
merrily, merrily, merrily, merrily
Life is but a dream
Row, Row, Row your boat,
Gently down the stream,
If you see a crocodile
don't forget to scream
aaahhh!
Try this:
Rock your baby side-to-side or gently bounce their legs in rhythm with the song. Movement plus music = early coordination, focus, and joy!
Got siblings? Let the older one sit behind the baby, or place baby between your legs, and gently rock together while you sing. It’s a lovely way to build closeness and connection.
Did You Know?
Babies don't realise they are separate from their mothers till around 7 months, and they may not recognise themselves in the mirror till around 18 months, so mirror play is very interesting and funny when they get together with their little mirror friend!
✨Bonus activity: On a nice day, go and lay outside under the trees next to baby (their eyes might be able to adjust to the brightness better now). Just watch the leaves move in the breeze together, a calm moment while helping build attention, focus, and early understanding of cause and effect.
Social & Emotional Skill Building
Your baby is learning that relationships are a two-way conversation. When they smile, coo or make a sound, pause and respond as if you're having a real chat. These back-and-forth interactions help your baby feel heard, build secure attachment, and lay the foundations for language and social skills.
✨ Remember
Your baby doesn’t need perfection, they need you.
Every kick, every gaze in the mirror, every little movement is a learning moment.
You’re building connection, focus, and confidence, one playful step at a time.
Your doing beautifully 💛
