Congratulations for your 3-month old baby! At that age, your baby is more responsive to the surroundings and more playful. She will probably smile plenty and make funny noises trying to imitate the sounds around her. Keep communicating with her. Stick to simple words and sentences. That is the easiest way for baby to learn to speak. Don’t go over board and stop when you see that she feels tired.  



It happens with some babies to experience growth spurts. Signs of that is a moody baby, lack of sleep at night or extra hungry baby. At that age tho the spurts are temporary



The average weight for a 3-month-old baby boy is 14 lbs or 6.4 kg and for the baby girl is 12 lbs 14 oz or 5.8 kg. At her third month probably she has gained about 1.5 to 2 pounds. Again you shouldn’t stick exactly to the averages but make sure the baby grow happens in a steady and healthy rate.



The average length for 3-month-old baby boys is 24 1/4 in or 61.4 cm and for baby girls 23 1/2 in or 59.8 cm. With a healthy rate, your baby should’ve grown by 1 to 1.5 inches.  



Straight to the point. Your 3-month-old baby will sleep around 15 hours a day. Of those 15, 10 goes for night sleep and 5 for 3 daytime naps.

Bottled-fed baby should have an intake of five ounces, six to eight times a day. If you breastfeed your 3-month-old baby probably, you will do it every 3 to 4 hours, but of course, every baby is different, so that isn’t an absolute figure. To find out if he feeds enough, check the diapers. 5 soaking wet diapers is typical. Don’t worry if it takes your baby less time to breastfeed. This is due to the efficiency he develops over time. Remember, a healthy rate of growth is most important. Water and solid foods aren’t allowed for a 3-month-old baby. Downloadable feeding schedule checklist  




At 3-month-old  her sight keeps developing, and now she is getting better at tracking objects.


From 3 months to around 6 months, the baby will start putting things in her mouth. That's her way to sense different textures and tastes.

At this age, the temporal lobe of the baby's brain is catching up. It helps with hearing, language and smell. At this point when the baby hears your voice, he will turn his head and look directly at you. Don't worry if she loses concentration quickly. That might not be because she can't hear you but because she had enough stimulation.

At 3 months of age, your baby will use his nose to sense and recognise different people, whether it's someone he knows or a stranger. If he is scared of someone, he will start crying or kicking with legs.


Your 3-month-old baby can now tell the difference between soft and hard. Also, he enjoys soft touches like gentle tickling. CHECKLIST FOR 3-MONTH-OLD BABY 4-Month-Old-Baby-Milestones
