Your Baby's 5th Month
Learn about your baby's development at weeks 18-21
Raspberries and Bubbles
Baby has discovered many sounds that she can make with her tongue and lips. You may observe her delighting in bubbles and razzing sounds, sometimes even as she drinks or eats. These sounds may make you laugh or turn away, but they are the precursors for language and communication. She is exploring what sounds she can make, and you probably hear the same sounds over and over. She is practicing! (Learn more about Baby’s language milestones in the first year.)
Developing Sense of Humor
Another precious sound often heard around this time is Baby’s first laugh. Without knowing, you may do something silly that tickles her funny bone and out come the first chuckles. These are priceless sounds that most parents want to hear again and again. Your wandering fingers all over her pudgy belly, accompanied by the inevitable parental “gitchee-gitchee-goo” are bound to entice more giggles. Another way to make a baby laugh is to laugh back at her jokes. If she thinks you or she has done something especially silly, laugh with her. There is always time for a few shared belly laughs with your baby.
Does your baby smile when you sneeze? Perhaps because of the funny sound or the contorted expression on your face. If you repeat the sound that you just made, “Ha-Choo,” it sounds a lot like a popular vowel-consonant combination of babies, “Ah-Goo.” Some babies repeat this sound over and over. Say it back. She’ll love the attention and think she is having an important conversation. Try to figure out if she is using a particular sound when she is hungry, tired, or wants to play. These are important sounds and she is learning how to use to tell you what she needs.
Physical Development (Large Motor)
Around this time, a lot of babies enjoy being put into a sitting position. Baby loves this vantage point as she can watch her own body and all the interesting things around her. She probably has a somewhat curved back and may put her hands in front of her to prop herself up. She is getting stronger every day.
Occasionally she may straighten up or let go of one hand to grab a toy. You may want to surround her with soft cushions in case she topples over. She will be thrilled when you sit beside her. Watch how proud she is to be in the same position as her parents. Now she is ready for sitting in the high chair and joining the family at meals. This is a major accomplishment that makes a baby feel like part of the family. (Check out what sitting without assistance looks like!)
Physical Development (Small Motor)
If your child is enjoying her experience in the high chair, you may want to offer her a sippy cup. Make sure you offer her a smaller sippy cup that she can easily hold using both hands clutched to handles. In the beginning, there will probably be a fair amount of liquid dripping down her chin, making her wet. (Use these tips for introducing baby a sippy cup.)
And beware because just as she will learn to drink from the cup, she will also learn that it can be hurled and then lands with a loud sound. (“Hey, this is fun!”)
Starting Solid Foods
Between months four and six, many parents wonder about starting solid foods. Pediatricians agree that up until she is 9 months old, your baby gets all her required daily nutrients from breast milk or formula. It is important to recognize that there is no calendar-specific time for you to start your baby on solid food. Some babies are very content with breastfeeding and show no interest in food until past six months. But around this time some babies become curious about what they see their parents eating and want to know more about food.
There are some specific signs that indicate if your baby is ready to be introduced to solids. First, is she interested? Often babies at this age will eye your food, touch your plate, pick up a piece of food, examine it, and try to put in their mouths. Pretty clear that baby is interested, right?
There are also some anatomical signs if baby is ready:
- Baby must be able to hold up her head well. If there are any doubts about her ability to do so, wait on offering solid food.
- You might notice baby’s tongue-thrust reflex to push out solid food. This reflex protects baby from choking on solid matter and often goes away around four to six months.
- Babies must learn the skill of pushing solid food to the back of the mouth so that it can be swallowed.
- Baby’s lower lip needs to have the coordination to be able to draw food off of a spoon.
- Gastrointestinally, a baby’s intestines must be mature enough for solid food, meaning they are able to produce certain digestive enzymes to process the food.
Nevertheless, you may be curious about your baby’s reception to solid food. There are specific foods that are recommended for a baby’s first experience. Think about the consistency; go for foods easy on the digestive system and taste buds. Parents often like to start with cereals, rice or barley, mixed with breast milk or formula. Other popular first foods are mashed up bananas, squash, sweet potatoes, applesauce, pears, and carrots either prepared by you or from a jar.
Watch your baby’s reaction to these foods. If she is pushing out with her tongue, chances are she is not ready for solids. Don’t worry, in no time, she’ll be ordering from the kids menu.
Part of the experience of eating solid food is exploring the food. This includes using fingers and whole hands to feel the food and eventually try to put it in her mouth all by herself. How much you can tolerate of Baby’s exploration of food is an individual family decision; however, it is important to remember that it is a perfectly normal part of development and helps her master the art of finger feeding. Our advice: Put a huge bib on her, let her go for it, and hose her down when she is done. Bon appetit!
