I did the self soothe thing with both my kids. Now I just put them in bed and they put themselves to sleep without a fuss anymore. As long as I put on some soft music and give them a sippie cup of milk they are perfectly fine.
The only way I could get my baby to sleep is by putting her in her baby swing. That's her new crib lol
Once she's changed, fed, and all sleepy, she sleeps forever in it. I have to wake myself up throughout the night to feed her because she is so comfy she won't wake up herself lol
