Although the child in pregnant woman abdomen has not been born, but had had life, the pregnant woman that is about to become mother wants to know growing course of the child very much certainly, the child blossoms how.

1, pregnant woman how to answer the frequency of observation and computational quickening?

The method of frequency of quickening of commonly used computation is very simple, pregnant woman can choose a fixed time in the evening everyday (be like everyday in the evening at 9 o'clock) , in face the quickening time that 1 hour measures before sleeping. If conditional person, it is better to can measure quickening number each during early, medium, evening. Of course, fetal quickening computation, can make a mark that reflects fetal safety only.

　 2, how to measure fetal weight and low weight

Fetal grow how oldly now? Prospective parents is the care of what kind to his child! So does oneself child have after all how old? How can you measure again go out?

The main mark of fetal size is fetal weight and height, especially weight is the serious content that measures fetal development state of affairs more. Ample fetal weight and height are the main condition with fetal development maturity, strong vitality. The method that measures fetal weight is more, some is quite complex, but all methods are rude estimation, answer so with handy for beautiful. Have two kinds of simple methods roughly at present:

(1) is fetal show a share first (fetal most the part of lower part, fetal head or fetal buttock) , when having notting enter the pelvis, usable and undermentioned formula: Fetal weight (gram) height of = uterus bottom (centimeter) L55 of one 12 × .

(2) is fetal when showing a part to already entered the pelvis first, with undermentioned formula: Fetal weight (gram) height of = uterus bottom (centimeter) one 11 × 155.

For example, pregnant woman is gravid 40 weeks, palace bottom height is 33 centimeters, with afore-mentioned (2) formula computation gets fetal weight to be 3410 grams, explain fetal growth is good.

The growth rate of fetal height is more constant, even. The method that calculates fetal height is the height end the uterus that uses pregnant woman will calculate estimation. As the addition of gravid month, the height of uterine bottom rises gradually. General and gravid 8 Zhou Shi, uterine bottom can be felt on pubic bones; When going to 16 weeks, palace bottom is mixed at pubic bones between umbilical ministry, 20 ～ 22 Zhou Shida hilum ministry; 32 Zhou Shi at hilum and sword dash forward between; 36 weeks can touch a sword dash forward below. The clinician regards judgement as the basis of fetal month with height.

If be in,pregnancy is caused as a result of a variety of reasons hidebound, can affect fetal growth development, happen even hidebound, the weight when as a result is born is apparent under normal baby (normal baby) of 3000 grams above, be called " mature low weight " low weight because a priori is insufficient, right prepotent it is very adverse, the deformation of he and the addition that surround rate of newborn baby sicken, transmissibility, baby after be born grows amount of cell of logy, head is little, ability difference learns to be concerned etc after enter a school even, because this should avoid mature low weight as far as possible happen.

Cause low weight the reason is very much, but the nutrient state that basically is pregnant woman. Say commonly, as a result of the change of physiology and need, the pregnant woman addition as gravid month, appetite also can increase gradually, the quantity of heat that down to absorbs 500 kilocalorie of 300 ～ more everyday is not difficult. But, if of pregnant woman prandial unreasonable, of together with pregnant woman carry feed, the reason such as partiality for a particular kind of food, avoid certain food, can cause the inadequacy absorbing a person of nutriment, make fetal weight under normal. Accordingly, gravid woman should notice to increase nutrition, should notice alimental diversification particularly, in order to make sure fetal and congenital growth is good, this is prepotent important segment. Of course, pregnant woman nutrition also answer proper, otherwise gain weight is too fast, fetal too long, also can increase the difficulty in pregnancy burden and childbirth.
