Emavikini la-24
lujwabu lwemehlo luyavuleka
futsi ifithasi iyacwabita
nakukhona lokuyetfusako.
Lokunyakata lokwenteka nakukhona
umsindvo lomkhulu longakalindzeleki
kusheshe kube khona
kumafithasi lamasikati.
Labenta luhlolo babika kutsi
kuba semsindvweni lomkhulu
kungaba nemphumela lomubi
emphilweni yefithasi.
Umphumela lomubi
lovela masinyane
ufaka ekhatsi kwenyuka
kwelizinga lekushaya kwenhlitiyo
sikhatsi lesidze,
kugwinya kanyenti,kanye nekugucuka
masinyane kwendlela ifithasi
letiphetse ngayo.
Imiphumela lemibi lengavela
esikhatsini lesitako ifaka ekhatsi
kungeva etindlebeni.
Lizinga lekuphefumula kwefithasi
lingenyuka lize lifike
ku-44 wemahlandla lalandzelanako
ekudvonsa nekukhipha umoya ngeliminithi.
Ngekuhamba kwanyangatsatfu
wesitsatfu wekutetfwala,
kukhula masinyane kwengcondvo
kudla ngetulu kwa-50% wemandla
lasetjentiswa yifithasi.
Sisindvo sengcondvo senyuka
emkhatsini wa-400 na 500%.
Emavikini la-26
emehlo akhipha tinyembeti.
Tinhlavu temehlo tibona kukhanya le ekucaleni emavikini la-27. Lokunyakata loku kukala bunyenti bekukhanya lobufinyelela kurethina iphilo yemuntfu yonke.
Tinhlavu temehlo tibona kukhanya le ekucaleni emavikini la-27. Lokunyakata loku kukala bunyenti bekukhanya lobufinyelela kurethina iphilo yemuntfu yonke.
Tonkhe tincenye letidzingakalela
kutsi umuntfu akwati kunuka
tiyasebenta.
Lucwaningo lolwentiwe ebantfwaneni
labatelwe ngembikwesikhatsi
luveta kutsi umntfwana ukwati
kuva kutsi kukhona lokunukako
le ekucaleni emavikini la-26
ngemuva kwekwakheka kwembewu yemuntfu.
Kufaka intfo lenongotelako emantaneni e-amniyoni kwenyusa lizinga ifithasi legwinya ngalo. Kuphikisa loko, kuba khona kwehla kwelizinga ifithasi legwinya ngalo nangabe kufakwe intfo lebabako. Lokulandzela loko kuvamisa kuba kuntjintja kwesimo sebuso.

Ngekusebentisa luchungechunge
lwekunyakata ngekutsatsa tinyatselo
lokunjengekuhamba,ifithasi
ishaya goboluphonjwana.
Ifithasi ayisabonakali
kushwaphana kakhulu
njengaloku lamanye emafutsa
langakasetjentiswa ngumtimba
akhela ngaphansi kwesikhumba.
Emafutsa adlala indzima lebalulekile
ekugcineni lizinga lekushisa kwemtimba likahle
nasekubekeni emandla ngemuva
kwekutsi umntfwana atelwe.
Chapter 44 7 to 8 Months (28 to 32 Weeks): Sound Discrimination, Behavioral States
Emavikini la-28 ifithasi
iyakwati kwehlukanisa
emkhatsini wemsindvo loshaya
etulu naloshayela phansi.
Emavikini la-30, kunyakata kwekuphefumula
sekwetayeleke kakhudlwana kubonakala
futsi kwenteka 30 kuye ku-40%
wesikhatsi kufithasi leyetayelekile.
Ngekuhamba kwetinyanga leti-4
tekugcina tekutetfwala,
ifithasi iba nesikhatsi lapho
inyakata shengatsi iyati kutsi yentani
lokulandzelwa sikhatsi
sekuphumula.
Letindlela leti tekutiphatsa
tikhombisa indlela lecake
ngayo nalechubeke njalo yandza
yeluhlelo lolukhulu
lwekuphefumula.
Chapter 45 8 to 9 Months (32 to 36 Weeks): Alveoli Formation, Firm Grasp, Taste Preferences
Emavikini cishe la-32,
i-alviyoli sibili,
kumbe tinhlayiya
"tetikhwama" temoya,
ticalisa kukhula emaphashini.
Itawuchubeka yakheke kuze kube
minyaka le-8 umntfwana atelwe.
Emavikini la-35 ifithasi
seyibamba kahle icinise.
Kubonakala shangatsi ifithasi letfolwe
tintfo letinhlobonhlobo isesesiswini
kuyenta itsandze tinongo
letitsite ngemuva kwekutalwa.
Sibonelo, lawo mafithasi
bonina bawo bebadla i-anisi,
lentfo leyenta kutsi ilikhorayisi
inambitseke ngalendlela lenambitseka ngayo,
akhombisa kutsandza i-anisi
ngalesikhatsi satelwe.
Bantfwana labasandza kutalwa
labangakayitfol i-anisi basesesiswini
bona abayitsandzanga i-anisi.
Chapter 46 9 Months to Birth (36 Weeks through Birth)
Ifithasi ngiyo lecalisa
Umsebenti wekutalwa kwayo
ngekutsi ikhiphe linani lelikhulu
lehomoni lebitwa ngekutsi yi-estrojeni
ngaleyo ndlela icalise ingucuko
yekusuka ekubeni yi-fithasi
ibe ngumntfwana losandza kutalwa.
Kutalwa kwemntfwana kwenteka ngekufinyela ngemandla kwesibeletfo, lokugcina ngekutalwa kwemntfwana.
Kutalwa kwemntfwana kwenteka ngekufinyela ngemandla kwesibeletfo, lokugcina ngekutalwa kwemntfwana.
Kusukela ekwakhekeni kwembewu
kuze kufike ekutalweni kwemntfwana
kanye nangale kwaloko,
kwakheka kwemuntfu yintfo legucugucukako,
lechubekako, kanye nalecakile.
Lwati lolusha loluvelako mayelana
nalesehlakalo lesi lesimangalisakothis
luchubeke njalo nekukhombisa indlela
kwakheka kwefithasi lekubaluleke ngayo
ekuphileni kahle kwemuntfu
imphilo yakhe yonkhe.
Njengaloku kucondzisisa kwetfu kwakheka kwemuntfu losengakatalwa kuya ngekutfutfuka, kanjalo nelikhono letfu ekwenteni imphilo lenhle ibe ncono - kuto totimbili tikhatsingembikwekutalwa nangemuva kwekutalwa kwemntfwan.
