WHAT IS MY BABY'S IDEAL WEIGHT?
The issue of baby's weight is one most mums are very concerned about before delivery, after delivery and for the first few years of the child's life.....many are even concerned up to the adolescent period.
Not only Mums are concerned...we as Paediatricians are concerned as well.......
This is because the underlying factor is 50% of all under-five deaths is MALNUTRITION which usually manifest as weight less than what is expected for the child's age
SO it is key we KNOW and MONITOR our children's weight so we can identify when there is a problem early so we can seek early intervention and avoid diseases and deaths that come with malnutrition
I will start with what is the ideal weight at birth......then how the weight should progress and what the average weight of the child should be.....I will allude briefly to what can make the weight to be less than expected or more than expected and what to do when we have any concerns about the weight of our children
AT BIRTH.....the BIRTH WEIGHT normally ranges from 2.5kg to 4.0kg
Any weight below 2.5 is LOW BIRTH WEIGHT
Any weight above 4.0kg is LARGE FOR AGE BIRTH WEIGHT or MACROSOMIC or BIG baby
After birth, Babies FIRST LOSE WEIGHT in the first 10 days.....before regaining their birth weight by the 14 day......
So it is not unusual or babies to lose weight first....Don't panic.....This is as a result of loosing fluids, inadequate feeds at the beginning and so on....but as the feeding become established they regain their birth weight at 2 weeks
Babies gain weight thereafter usually about 30g per day for term babies; 20g per day for preterm babies
That is roughly about 1kg per month for term babies and 600g per month for preterm babies
At this rate...Children DOUBLE their birth weights at 5 -6 months and TRIPLE their birth weights at 1 year
Remember we are talking AVERAGELY.......Some babies do gain a little more; others a little less......So You don't have to worry as long as your baby's weight falls into the 80% - 120% range of the average weight I mention; it is OKAY!!!
So let us do a little maths......Average weight at birth is 3.5 kg.......at 5 months, doubling will mean weight of 7kg and triple of weight at 1 year will mean weight of 10kg
We have formula and charts of estimating the average weights of each baby....We also have online calculators you can use. Most Mums have Immunization cards and in this card is a WEIGHT CHART that is plotted each time your baby is weighed to know if your baby's weight is increasing as it should be
PLEASE ALWAYS INSIST YOUR BABIES ARE WEIGHED AND THE WEIGHT MEASURED AND CHARTED ON THE CHARTS .....Unfortunately most of us mums see these cards as important for immunizations record only instead of weight or GROWTH MONITORING
▷1 YEAR.....AVERAGE WEIGHT IS 10KG
▷2 YEARS AVE WEIGHT IS 12 KG
▷3 YEARS AVE WEIGHT IS 14 KG
▷4 YEARS, AVERAGE WEIGHT IS 16KG
▷5 YEARS AVE WEIGHT IS 18KG
▷6 YEARS AVE WEIGHT IS 20KG
It is important to note that weight varies based on genetics, nationality, gender etc.....apart from the food intake
You can use online calculators....Just input your baby's weight and gender.. it will bring out the ideal weight.....average....remember 80 - 120% of the ideal is STILL NORMAL
Alternatively use the Growth Chart in your Immunization booklets or cards and trace out the weight on the vertical line that corresponds to your babies weight on the curve of 50th...which is the average
It is important to make sure your babies weight do not remain STATIC OR SAME....OR EVEN WORSE DROP BELOW WHAT IT WAS BEFORE......those are very bad signs
IDEALLY YOU SHOULD WEIGH YOUR BABIES MONTHLY IN THE FIRST YEAR OR AT EVERY VISIT TO THE HEALTH FACILITIES
If your baby is NOT GAINING WEIGHT (ORANGE SIGNAL); PLEASE SEE A DOCTOR......IF YOUR BABY IS LOOSING WEIGHT (RED SIGNAL) SEE A DOCTOR URGENTLY!!!
