My baby boy is getting too big for his bouncer chair & his swing. He's used to those things to fall asleep in. I've been told to put him in his crib & just let him cry but it literally gets no where with him crying & screaming. I have no idea what to do. He loves his bouncer & all he wants is to sit, play, & sleep in his bouncer. He's pretty much already quite big for his bouncer. I've tried rocking him in my arms & that doesn't necessarily work at all. It's basically a hit or miss with me. Any ideas please?
