Child Development Notes for Year 10-11 OCR Exam

Child Development Basics

Fertility changes dramatically with age, especially for women. A woman's egg quality and ability to conceive naturally decline as she gets older, which is why doctors pay close attention to maternal age.

After 35, women are classified as geriatric mothers - don't worry, it's just medical terminology! The NHS reports that half of couples struggle with fertility issues when the woman is over 35, and this increases further at 40. Meanwhile, men can produce sperm from puberty until death.

Several factors influence couples' decisions about having children. Financial stability, relationship quality, parental age, and even peer pressure all play a role. Some couples also seek genetic counselling if there's a family history of inherited conditions, as older mothers face higher risks of chromosomal conditions like Down's syndrome.

Remember: Planning ahead gives you the best chance of a healthy pregnancy, regardless of when you decide to start a family.

Preconception Health and Contraception

Your health before conception massively impacts your chances of getting pregnant and having a healthy baby. Smoking, drinking alcohol, and drug use can all harm fertility and early pregnancy development.

Weight matters too - being overweight can mess with ovulation and make fertility treatments less effective, whilst being underweight can disrupt periods. Three crucial nutrients for women planning pregnancy are iron, folic acid, and calcium.

Barrier methods of contraception include male condoms (98% effective), female condoms (95% effective), and diaphragms (92% effective). These physically prevent sperm from reaching the egg and many protect against STIs too.

Top tip: Male condoms are your best bet - they're nearly 100% effective when used properly, protect against infections, and are free from your GP or family planning clinic.

Hormonal Contraception and Early Pregnancy

Hormonal methods work by changing your body's natural hormone levels to prevent pregnancy. The combined pill, progesterone-only pill (POP), intrauterine system (IUS), and contraceptive implant are all over 99% effective when used correctly.

These methods don't protect against STIs but offer excellent pregnancy prevention. Some need daily attention (like pills), whilst others like the IUS and implant work for years once fitted.

Understanding pregnancy timing is crucial: an embryo becomes a foetus at 8 weeks after conception. In the UK, terminations can legally take place up to 24 weeks, though most happen much earlier.

Key fact: Hormonal contraception is incredibly effective, but you need to use it consistently and correctly - missing pills or not replacing implants on time reduces effectiveness.

Early Pregnancy and Antenatal Care

Recognising early pregnancy signs helps women get proper care quickly. Look out for tender breasts, fatigue, nausea (morning sickness), frequent urination, and missed periods - though symptoms vary hugely between women.

Antenatal care involves regular clinic appointments to monitor both mother and baby's health. Your first appointment happens at 8 weeks, where healthcare professionals provide guidance, support, and essential health checks.

A team of professionals supports pregnant women: midwives provide most routine care, GPs handle general health issues, and obstetricians (specialist doctors) manage complicated pregnancies. Routine checks include monitoring baby's heart rate, mum's blood pressure, urine tests, and weight monitoring.

Most women can choose where to give birth, but hospital births might be recommended if there were previous complications, the baby's premature, or there's risk of conditions like preeclampsia.

Remember: Antenatal care isn't just about checking for problems - it's about preparing you for parenthood and ensuring the healthiest possible pregnancy.
