Our baby is very clingy. I'm talking right out of the womb we couldn't put her down and she hated her arms swaddled. Lots of contact napping and difficult long nights. The first couple months were rough but once I took the newborn class there was no looking back. The very first day of implementing her training she took every single nap in her crib. By the time it was time to "Sleep Train" I barely had to do anything at all. We took every class, but she was already a great sleeper at five months. It didn't change my relationship with her at all, she is still VERY CLINGY but we are well rested and clingy. The perfect combo.
