I've come to the conclusion that I'll never sleep more than 3 hours in a row ever again. My son has been up for hours crying, being happy, being angry, being hungry, not being hungry, being in pain, not being in pain, you name it. I have no idea.
We fed him and bottle, breast fed him, sang to him, gave him massages, held him, let him sit there and work it out, let him play with toys, changed his diaper, burped him, did leg exercises so he could fart out trapped gas, played music, read to him, give lots of kisses and hugs, you name it.
I'm starting to hate people who say their kids sleep through the night right away. The more I talk to them and ask questions, the more I realize they're either painfully lucky and telling the truth, or they're ignoring their kid or feeding them cereal milk which is a choking hazard on every pediatric website.
My friend told me his daughter sleeps through the night and finally he admitted that he put her in her own room at 3 weeks old and doesn't go in to check on her if she cries. She's a year older than my son and my son is heavier and taller than she is.
I will say that parenting is a real eye opener to the type of people your friends are.
