Trying to explain to my 22 year old cousin who is kind of "slow" that having a baby is not easy is NOT EASY. I get it her choice but I believe she wants a baby for all the wrong reasons. She thinks its cute to be pregnant, to walk around with a baby, to dress baby up this and that. What she won't understand is, even though her boyfriend is excited they MIGHT be expecting, doesn't mean he might not want it after all and leave her. My aunt (her mom) passed away last year 7 days after her birthday. She's left at 22 years old being a mother to her 12 year old sister. My cousin has a disability. Shes partially deaf also. She thinks because I have a baby and make it seem easy, it'll be easy for her..
