My daughter slept through the night at 8 weeks. I know, hate me. I deserve it.
BUT, she was swaddled. Now, she can bust out of that thing, no problem (5 months old), to the point that I don't think she should be in it anymore. Seems like she truly outgrew the practice. One arm isn't an option. She can roll on her stomach easily like that, but can't seem to roll back.
Now, unswaddled, she uses her hand to bat the pacifier out of her mouth 12-15 times per night. I'm in hell. The second I put it back in, back to sleep.
I am not going to let her cry for 8 hours. She starts to gag and turn purple after 2 minutes of real crying. Not my parenting style.
Can't put the bink in herself, because she only like the ones that are orthodontic and have a "right" and "wrong" side.
