We went thru a stage of 2- 2.5 hourly wakings, prolly around same age, gradually she got to 3 hourly.

In the end when she was on 3 good size solids a day I decided enough of that and cut out the 2am feed.
They wake so often cause they don't know how to resettle without the breast so we spent 2 nights just cuddling/ patting and 3rd night she slept for 6 hour period.
