In twin pregnancies, women gain about 10 to 18 kg, meaning they weigh 3 to 6 kg more than in a single fetal pregnancy. Despite the increase in weight gain, twins should be born with an average of 2. 4 to 2. 7 kg, a weight slightly less than the desired 3 kg when giving birth to a single baby.
When the triples are pregnant, the average total weight of the box should be 22-27 kg, and it is important to increase 16 kg in the 24th week of pregnancy to avoid complications for babies, such as low weight and small size at birth.
