Do you realize the responsibilty falling on your shoulders too while putting a baby in her womb? If not, lemme walk you through.
Right from the day a foetus starts growing, women start feeling morning sickness. A feeling of Vomiting is there probably all the time due to which they can't even eat properly. Backache is also there cuz again the foetus is growing. Bladder & bowel problem. Changes to hair & skin.
Fatigue all the time.
On top of everything, Women feel headache probably all the time in their pregnancy. They can't even stand for a longtime cuz the moment they do, headache hits in & they might faint. Hence they can't even cook for long. They face problem with how they've to sit in washroom cuz baby is in the womb that isn't supposed to feel any external pressure, not even due to the sitting postures. And they've do this for 9 months. Also, Plenty of them has to go through an operation to give the baby birth (Don't just read. Visualize it so that you can get to know how pregnancy feels like).
Point is, Responsibilty of all that care that comes with making a woman pregnant, is what makes you a father. So, if you don't realize your responsibilities, you'd fail to be a father.
