Nursing issues

Hey ladies! I’m in need of some advice. Going to a Lactation consultant today so we will see what she says as well. For the last week my LO, 14 weeks, has been going through a semi nursing strike if that is possible. The only way he will nurse from the breast, EBF, is if he is tired or if I’m waking around. There has been no change in my diet, he is not going through a wonder week, doesn’t seem to be teething, I have good milk production. I want to breast feed for a year at least so I’m hoping it’s a phase. Not sure what to make of it. Anyone else experience something similar?
