My baby is 10 months old and currently breast feeds on waking up in morning, before bed and after lunchtime nap. I'm about to go back to work and wonder if I can drop the 3pm feed (replace with formula) 4 days a week when I'm not with him, but keep it on the other days? Or will my supply reduce if I don't feed on the 4 days-meaning that I can't feed on the 3 days I'm with him? Not keen on expressing but will do if necessary to keep up supply.
