"Just because it's hard for you doesnt mean it isnt what is best for them....babies will surprise you with how self sufficient they can be." I completely agree. It has been so tough for me to ignore the crying but in the end it all works out for the better.
Is your baby swaddled when sleeping? This helped our daughter to sleep longer periods of time. Once she outgrew the swaddle due to rolling over we switched to the sleep sack. I was nervous it wouldn't work as well but finding the right one was the key. We use the zipadee zip and it worked like a charm! She felt so cozy that she didn't cry much at all. Hope this is helpful for you!
