How would an oviparous creature know when to lactate?

The platypus do it, so it can and is done, some how. It would be a waste of energy to be lactating the entire time after the egg is laid up until it hatches, so how does my alien race know when to start?

The aliens are an odd mix between mammal and bird. The egg is about the size of an ostrich egg, but takes about 3 months to hatch, give or take a week. Would it be an instinctive timing thing, or would there be another trigger? I'm willing to use some fictional magic on this if need be.
