Umlinganiselo wokuphakama komntwana kwiinyanga ezi-3
Le parameter, kunye nobukhulu, ixhalabele kakhulu ngonina onomdla. Ukutyelela ngenyanga ugqirha kuhambelana neendlela zokukhula, kunye nokulinganisa umntwana. Iziphumo zifakwe kwikhadi.
Kwi-intanethi, unokufumana iithayibhile zokukhula kwabantwana ezinyangeni ezintathu, kunye nakweyiphi enye iminyaka. Kukholelwa ukuba abafana beli minyaka banokukhula ukuya ku-59 cm, kunye namantombazana ukuya kuma-58 cm.
Kodwa kuyafaneleka ukuqonda ukuba zonke ezi zikhombisi zilinganiswe. Ngokweziphakamiso ze-WHO, izikhombisi eziphakathi kwe-57.3 ukuya ku-65.5 cm kubafana kunye no-55.6 ukuya kuma-64 cm ngamantombazana babonwa njengesiqhelo. Nangona abantwana abasempilo banokuhluka kakhulu kule parameter. Yintoni eya kuba kukukhula kumntwana kwiinyanga ezi-3, kuxhomekeka kwizinto ezinjalo:
- imfuza;
- ukukhula ekuzalweni;
- isimo sempilo;
- Uhlobo lweentlanzi zokutya ( ukuncelisa okanye ukutya umxube ).
Unokuphinda uhambe ngeetafile, ezibonisa ukwanda kweenyanga.
Ngoko, kucatshangelwa ukuba kwiinyanga ezintathu ukukhula komntwana kufanele kwandiswe ngu-2.5 cm kwiintsuku ezingama-30 ezedlulileyo okanye 8.5 cm kwixesha elipheleleyo emva kokuzalwa. Kufuneka kukhunjulwe ukuba la manani awananto.
Abazali bafanele baqonde ukuba ipharamitha ebaluleke kakhulu ekuhloleni ukuphuhliswa komntwana ngumqathango wayo. Ukuba umntwana unesidlo esifanelekileyo, ubonisa umsebenzi, isitulo sakhe siqhelekileyo, kwaye ugqirha akabonanga nayiphi na impazamo empilweni, ngoko akukho mfuneko yokukhathazeka malunga nokungafani phakathi kwamanani athile.
