I’ve heard of tons of different ways to train your infant to sleep, but none are as good as the one I read about: Wait It Out.
It suggests that instead of becoming upset that your infant won’t sleep when you want her or him to, perhaps you should listen to your baby telling you that they need you to hold them and wait out the crying until they feel comfortable, safe and relaxed. After all, this is a brief period in time (though it feels like forever after your 93rd day of sleeping in three hour increments! Ugh!) when you look at the span of their whole life. The author says it better than I can:
Maybe you have reflux that makes laying down painful. Maybe you have a belly ache. Maybe you are anxious because of a noise, or afraid of the dark. Maybe you simply do wish to be held because my arms are the safest and warmest place in your world. Maybe your instincts speak loudly to you in ways that you do not understand and you simply know that right now you need to be held in order to be calm.
The next time your baby is crying at 2am and you just want to lie them down in their bassinet or crib and sleep for a few hours, take a deep breath and try the Wait It Out Method. In a few years, you’ll be begging your little one to give you hugs and kisses. Appreciate them wanting you while you can.
