Question: 3 month old STTN?

At two months old, DD was giving me a 6-8 hour solid stretch at night. Usually around 10pm to 6am. Within that time frame. Now, at 3 mo she is sleeping a bit more, like 10 hours but she keeps waking up 2x a night, she will only go about 3 hours at a time. It is killing me. I preferred one 6-8 hour stretch over three 3 hour stretches. Why is this changing? Is this normal?

Maybe you need to bump up the amount in her bottle before she goes to bed. We did and DD goes from about 9pm-7am.

Sounds like my DD. She did her best sleeping at 2-3 months. At 6 months she sleeps 11 hours at night but is up between one and three times during the night. I can't get myself to do CIO so I don't know how to get her to wake less.
