Conception: egg released and meets up with sperm – happens in fallopian tubes 9 month (40 weeks) of development: 1 st trimester essential for foetal development 2 nd trimester – external genital organs begin to develop 3 rd trimester – earliest point at which foetus can potentially survive outside of womb

Placenta – sac that holds foetus and amniotic fluid Umbilical cord – connects mother and foetus – what goes in mother gets into baby Amniotic fluid – allows for baby to move and survive

Contractions – muscle cramps pushing the baby down towards the vagina Breech – bottom first, baby in V shape Natural or vaginal birth – baby delivered through mother’s vagina Caesarean birth – baby delivered with surgeon’s help through mother’s stomach
