Anna gave birth to her five healthy babies, who has grown fast, in a blink of an eye and beautifully. They turned 18 just after few months of being birthed, well same as Mika, who also found himself growing every night to 18 years, so this means, he's the same age as Anna's babies.
Oliver and Anna have never been happy, along with everyone especially Molly, Oliver's parents who wished they could've grown normally so that they could spoil them, and sometimes they would just sleep with them, and bond with them whilst they were few weeks old and as well as Anna's parents, who also welcomed Jonathan's Mika, since they would visit them by teleporting from time to time and the kids absolutely love and listen to their grandparents more than their parents, and they love spending their time at Anna's parents because of the farm mostly, than being in the cities in South Africa. The kids have been introduced to everything.
