2 month old sleep progress

Hey all, is my LO on track for her age? She goes to bed at about 1030, wakes at 2 or 230 am. That is her longest stretch. From there she will wake every 2 hours, so 3 total feedings. Not sure how to lengthen those 2nd and 3rd stretches?? She will eat the same amount as she does at bedtime.
