So I'm the last person to say that having sore muscles doesn't feel satisfying, but good workouts don't always HAVE to make you sore. Sore muscles just means your muscles were exposed to a stress greater than it's used to. Trying to make yourself sore all of the time reduces the ability for muscles to recover and can lead to strains and tears.
Here's why your baby needs 39 weeks before being born: * Important organs, like his brain, lungs and liver, get the time they need to develop. * He is less likely to have vision and hearing problems after birth. * He has time to gain more weight in the womb. Babies born at a healthy weight have an easier time staying warm than babies born too small. * He can suck and swallow and stay awake long enough to eat after he's born. Babies born early sometimes can't do these things.
