The sound of the baby making a strong hmmm can be caused by physiological factors, or can be caused by pathological factors such as bloating.
1. Physiological factors: the baby is lying down for a long time, there is no effective way of movement, so the sound of making a strong hmmm is actually a kind of stretching movement. At the same time, the transition between deep and light sleep will also appear similar sound.
2. Bloating: Babies with lactose intolerance, protein allergies or infections can become bloated and make the mmm sound.
3. Other discomforts: Babies may make the mmm sound when they experience any discomfort such as vomiting or fever.
There may be other reasons for your baby to make a mmm sound, so it is recommended that you go to the hospital in time for a complete examination to determine the cause of the problem, and then give targeted treatment or therapy.
