For those of you who latch, do you let baby rotate sides every 5 mins? My baby is 6 weeks old. The polyclinic nurse told me to rotate sides every 5mins.....I thought we are supported to nurse on one side since mature milk would have kicked in by now???

I don't practice every 5min, because I find it very disruptive on the feeding session and as what you've said, I want him to have access to hind milk. That said, I'll offer him the other side when he unlatches and ensure that I'll start with the other side at the next feeding session. If the rationale is to stimulate supply, one can pump after nursing as well.
