Kuremera kwemwana asati aberekwa chikonzero chakakosha kuitira kutarisisa kana fetus iri kukura zvakanaka, zvakakwana uye kazhinji. Icho chiremera checheche, izvo vanachiremba vanosangana pamwe nezvimwe zviratidzo, zvakadai sokukwirira, zviyero zvezvikamu zvemuviri wemuviri, palpitations, izvo zvinoita kuti zvive nyore kuziva mamiriro ezvinhu epanguva ino yekuzvitakura panguva yakakodzera. Nenzira iyo fetus inounganidza uremu hwemavhiki, chiremba anokwanisa kutonga kukura kwechecheche, uyewo kana iri pachena kune chero zvigadzirwa zvepatigenic.
Somuenzaniso, kana fetus inowedzera uremu hwevhiki zvakanyanyisa shure kwemaitiro, zvino izvi zvinogona kuva chiratidzo chekushaya nzara, zvose oksijeni uye zvokudya. Oxygen nenzara inogona kuva mumwana kana mukadzi achitsvuta kana kunwa panguva yekuzvitakura. Nzara yezvokudya inogona kuwira mwana nekuda kwekushaikwa kwemakemikari anodiwa zvidimbu. Kusava nemutoro kunogonawo kuratidza kuderera kwepakati pekuvandudzwa kwe fetus uye kunyange kutakura kunopera .
Izvo zvinoenderana nekurema kwakanyanya, izvo zvinoitika semugumisiro wehumwe kusakanganisika kana kushungurudzika mukurudzirwa kwechecheche. Zvechokwadi, mukadzi wese nemwana wake weramangwana ane chimiro chomunhu oga wemuviri, saka haugone kuisa munhu wose pasi pebha imwe.
Chii chinofanira kuva chiremera chemucheche vhiki imwe neimwe yekuzvitakura?
Kuti dzimwe nzira dzifambire pahutachiwana uye kutarisa kubudirira kwechecheche, pane dzimwe tsika dzehutachiwana hwema fetus kwemavhiki. Kazhinji, chiyero chose che fetus chinotariswa ne-ultrasound kuongorora, iyo inzira yakatendeseka uye yakakwana. Asi ultrasound inogona kuitwa zvishoma chete munguva yose yepamuviri, saka vanachiremba vanoona kuyerwa kwemucheche "neziso", vachiyera urefu hwemamiriro ekuberekwa uye kuenzanisa kukwana kwese kwemuviri.
Kuti urege kurasikirwa nekufungidzira, kuti mwana anofanira kuverenga zvakadini pane imwe nguva yehupamuviri, pane tafura chaiyo yehutachiwana hwemuchechi kwemavhiki:

Asi zvakakosha kuyeuka kuti zviratidzo zvakadaro hazvina kururama, asi zvinongoratidza. Nokudaro, kana kuongorora hurumende yakawanda yemwana, hazvina kukodzera kugadzirisa zvakananga. Mukuwedzera, tsvakurudzo yakadaro inofanira kuitwa neyanyanzvi anoziva.
Kazhinji kazhinji mwana ari pamuviri anorema kubva pa3, 1 kg kusvika ku3, 6 kg. Asi pane vana uye vane urema hwakawandisa, nokuti chimiro chemuviri chemwana chinokanganiswa nezvikonzero zvakasiyana siyana:
- kurara kwomwana;
- chikafu, utano hwakanaka uye kuvapo kwemaitiro akaipa emukadzi ane pamuviri;
- zvinogona kuitika pakurara pamuviri;
- nhamba yevana vari mudumbu.
Kutora uremu mushure memakumi maviri evhiki yekubata
Pasati vhiki ye20, kuyerwa kwemwana asati aberekwa hausi kukuru uye kunowanzowanikwa. Asi atova pamasvondo makumi maviri kuyerwa kwechibereko kune 300 gramu, uye pamasvondo makumi matatu mwana anorema kirogiramu yakawanda. Izvi zvakakosha, asi kana kukura kwakadaro kuyerwa kusingatariswi, zvino zvakakosha kubhadhara zvakanyanya izvi uye kuziva zvikonzero zvekusakwanira kukura kwechecheche. Pavhiki 38 yekutakura, uremu hwemucheche hunofanira kunge huri kana huri pedo nemakirogiramu matatu, izvo zvinoratidza kukura kwemuviri uye kugadzirira kwake kuberekwa.
