My baby girl has just turned 21 weeks and for about 6 weeks she was sleeping great I'm her own cot, going down at 7pm, awake between 2am and 4am for a feed; back to sleep then up at 8/8.30am. She was also self settling with NO TEARS which was great.

Now..... 😭😭😭

Now she still settles to sleep most of the time but not always, she's waking at about 1am then waking every 45mins to an hour 😭 I'm exhausted and as she will only breast feed and refuses bottles no one can really help me,... but I need some advice....

Has anyone else experienced this??? How can I help her get back to her good habits?

PS I don't think she's teething as she already had her 2 bottom teeth. I wouldn't expect the top any time soon but no sign anyway.
