I generally agree with you (I have a six and a two year old), but the sleep deprivation when the kids are babies is extremely debilitating. At least that part definitely gets better.

Good point. That initial period is hellish (and amazing) and it does taper off somewhat but settles on a new baseline of permanently elevated difficulty.

It's not bad if they wake up right next to a breast. Before long, they can feed without waking the parents. The sleep deprivation will be terrible if you have to stand up (get heart going), flip on the lights, walk to the kitchen, fumble around to mix and microwave, walk to the baby, sit with the baby, walk back to the kitchen to clean up, and then head back to bed.

Just another way natural is better than synthetic.

Exactly that. I have a 1.5 year old. We've been pretty much zombies for the first half a year, until she started sleeping through (most of) the night.

Sleep regressions are a thing. Our twins had a big one around 1.5 years old. I averaged 3 hours of sleep for about 2 weeks.

Problems will get less and less frequent, but they will get bigger and more serious.

Indeed! I was referring to sleep bit
