Is Your Baby's Mushy Stool Normal? Pediatric Insights on Infant Digestion

The baby's stool is mushy?

Hello Doctor: My daughter is currently 7 months old (weighing 7.5 kg and measuring 65 cm).
She has been switched to Abbott Similac and has started eating complementary foods, such as rice cereal, for about a month (before she was 6 months old, she only consumed Nestlé low-hydrolyzed protein formula.
Although she did not show any allergy indicators at birth, her skin is quite sensitive, and she frequently experiences diaper rash.
Occasionally, she develops slight rashes on her face and hands.
I wonder if this indicates an allergic constitution? However, she had a poor appetite with the Nestlé formula, which is why we switched to Abbott).
She typically has a bowel movement once a day, but for the past month, her stools have been mushy and unformed.
Is this normal? Should they be more formed? Do we need to change the formula brand? Is her current condition suitable for introducing complementary foods? If formula alone is not providing enough nutrition, what should we do? I seek to clarify my doubts.
Thank you!

Hello!
1.
The diagnostic criteria for atopic dermatitis include: (1) a family history of allergies, (2) recurrent rashes, (3) pruritus (itchiness), and (4) involvement of areas such as the cheeks, the flexural surfaces of the elbows and knees (common locations in young children).
Therefore, it is essential to consult a physician to confirm whether the skin rash is allergic in nature.
2.
If the stool is not well-formed daily, but the weight of the stool is less than 75 grams per day and the child's weight is stable and growing, this is still considered acceptable.
This is because some infants and toddlers aged 6 months to 3 years may have faster colonic motility, so there is no need to change the formula.
3.
If there are concerns about allergic predisposition, foods such as fish, shellfish, eggs, soybeans, peanuts, and tree nuts should be introduced after the child is over one year old.
Best wishes for health from Dr.
Chang Pei-Hsin, Chief of Pediatrics, Taoyuan Hospital, Ministry of Health and Welfare.

More Info

When it comes to infant digestion, particularly regarding stool consistency, it's important to understand that babies' digestive systems are still developing, and variations in stool can be quite common. In your case, your 7-month-old daughter is experiencing mushy stools, which can be normal, especially given her recent dietary changes.

Infants typically have softer stools than older children and adults, and this is especially true when they are breastfed or formula-fed. The introduction of solid foods, such as rice cereal, can also affect stool consistency. It's not unusual for the stools to become more mushy or even loose as new foods are introduced. This is because the infant's digestive system is still adjusting to processing different types of food.

In terms of what is considered "normal," baby stools can vary widely. They can be soft, mushy, or even somewhat watery, especially if the baby is consuming a diet that includes a lot of fruits or certain cereals. The key indicators of healthy stool include the absence of blood or mucus, and that the baby is not showing signs of dehydration or distress. If your baby is feeding well, gaining weight appropriately, and is generally happy and active, mushy stools may not be a cause for concern.

However, since you mentioned that your daughter has a history of sensitive skin and diaper rashes, it’s worth considering whether she might have a food sensitivity or allergy. The presence of red rashes on her face and hands could indicate a potential allergic reaction, particularly if they coincide with the introduction of new foods. If you suspect that she may have a food allergy, it would be prudent to consult with a pediatrician or an allergist. They may recommend an elimination diet or specific allergy testing to identify any triggers.

Regarding your question about whether to change formula brands, it’s essential to consider how she is responding to the current formula. If she is thriving, gaining weight, and not showing signs of discomfort, it may not be necessary to switch. However, if you notice persistent issues such as excessive fussiness, ongoing diaper rashes, or if her stools continue to be excessively loose, it might be worth discussing with your pediatrician. They can provide guidance on whether a different formula might be more suitable for her needs.

As for introducing solid foods, at 7 months, many babies are ready to explore a variety of textures and flavors. It's generally recommended to introduce a range of fruits, vegetables, and grains. If you are concerned about her nutritional intake, you can continue to offer a combination of formula and solid foods. The formula will provide essential nutrients while she gradually learns to eat solids.
In summary, mushy stools can be normal for infants, especially with dietary changes. Monitor her overall health, growth, and any signs of discomfort. If you have ongoing concerns about her digestion or potential allergies, don’t hesitate to reach out to your pediatrician for personalized advice and support. They can help ensure that your daughter is on the right track for healthy growth and development.
