Hello, good evening, Diana.
To find out if your child is overweight, underweight, or overweight, you can use the curve in the Card Towards Healthy in the pink book distributed by the posyandu, or you can use the curve created by the World Health Organization (WHO). Based on the WHO curve, the normal weight for children aged 21 weeks (5 months) for boys is 6 kg to 9.3 kg, and for girls it is 5.5 kg to 8.8 kg. From this curve, your child is actually still classified as having a normal weight, but is in the lower limit of the normal weight range. If your child's weight does not continue to increase while his age continues to grow, then it is very likely that your child will experience underweight later in life.
Underweight can be caused by:
Lack of nutritional intake, either because the food prepared is too small or the child refuses to eat.
Diarrhea that is long and often recurs resulting in inadequate absorption of food
Tuberculosis infection
helminth infection
congenital diseases, such as leaky heart, blood cell cancer, and others
Regarding formula milk, it can actually provide advantages and disadvantages. The advantage is that formula milk is expected to be able to meet the nutritional and vitamin needs needed by babies. However, formula milk (sufor) can also be an enemy of the mother for giving children to babies, for example in the case of babies who are too 'full' with the formula given so that babies tend not to eat anymore, or lactose intolerance (a type of sugar) in the intestines. baby, which causes the child to have diarrhea due to the lactose content in the formula.
To prevent the occurrence of underweight or malnutrition, it is recommended that you consult a nutritionist (can be done by a nutrition clinic at the puskesmas), or with a doctor (general practitioner or pediatrician) regarding the food menu and the amount that should be given to your child. when your child is able to get additional food other than milk (age 6 months).
Hope it helps, ma'am.
