Yes, it is quite common. Around 11 months, babies begin to associate hunger more strongly with solid foods, leading them to naturally drop breastmilk feeds. Follow your baby’s lead, but ensure you keep nursing before naps, at bedtime, and at night if you wish to maintain your supply. To manage potential engorgement during this transition, hand-express just enough to feel comfortable rather than pumping fully, which can signal your body to continue producing excess milk.
