They begin to develop suck reflex between 35 and 36 weeks. You will notice her click around this time. One day she won't the next day bam shell do it. Been in for 2 weeks so far hopefully only one more week as she's getting better at sucking. If she's able to continue putting her at your breast at least every 2nd feed if for nothing then associating breast with food.

Yeah she's a big prem. they predict she would have been close to 4kg if I went to term. My first was 1.6kg when born at 30 weeks.

It's a long but worthwhile journey
