Its fine if that's what they want. I want my kids to be no more than 5 years apart as opposed to having them all within 5 years, like my mother.
She had the 4 of us in 5 years. That aint happening over here. My brother and I are the same age for 2 weeks, were 11 months apart, another 2 years after him and another 3 years after her. I know other people with close ages and they love, Ive always hated it. Too damn close.
On the flip, I aint about to be teaching someone to ride a bike/ tie their shoes every 15 years. I think im too old for that lol im not even 30 yet but if I would've started 10 years ago, maaaybe
