What you're describing â latching, then pulling away and crying, especially at one time of day but not others â is a recognised pattern often called a nursing strike, not a sign your baby is rejecting you or your milk. At this age it's commonly linked to a faster or slower milk flow than she's used to, minor discomfort (teething can start this early for some babies), a stuffy nose making breathing while feeding harder, or simply a distracted, overstimulated moment. The fact that she feeds well in a sleepy state and in the evening is a reassuring sign that this is behavioural rather than a feeding-ability problem.
Next Steps
Keep offering the breast in calm, sleepy, low-light moments rather than when she's already upset, use skin-to-skin contact before attempting a feed, and keep expressing/pumping during the refused feeds so your supply doesn't drop while this passes. If it continues past 2-3 days, or you notice fewer wet diapers or reduced weight gain, see your paediatrician or a lactation consultant in person.
Health Tips
Don't force the latch when she's pulling away and crying â that tends to make a nursing strike last longer. If she seems unwell, feverish, or is feeding poorly even from a spoon or bottle, get her checked promptly.
