I should have more than 1 child

That's what my mother-in-law said when I told her that we're having a baby girl. Hubby asked her why we have to have more than one child and she said "for company". She told us not to have the baby alone by herself. I think she realized now that having one child is not good. She said that the girls as what she calls her co-residents at the assisted living facility were talking about their children and they got more than one child while my mother-in-law only have one. A friend of mine here in US said that her husband had a male friend who's an only son, no serious gf and had an elderly parents. He was sort of sad for not having a sibling to talk to and share responsibilities of taking care the elderly parents so he talked to my friend's husband whenever he felt sad and lonely about his life. His father died and after a year he was found dead at the yard. The neighbor said that it seems he's having a heart attack. My friend and her husband were shocked because they thought he's okay already. But before that, he was kinda depressed, sad and lonely. I guess he died first before his mother and I don't know what happen to his mother after he died. Hearing this story made me think to have more than 1 child. I know that it is difficult for me coz I have to do everything to take care of the kids without any help from family members/relatives or neighbors unlike in the Philippines. Besides, hiring a nanny is very expensive. Hubby mentioned to me in the past that having just 1 child is not good so he wants to have more than 1 child. He said that he doesn't want our child to be alone if we die. I just hope we can afford it.
