Actually, HO Lam refused my nipple when he was 8mth, reason unknown....so I become full pump mami. For first 1-2mths, I pumped 3 time a day, able to keep milk supply ga. But,when I skip lunch pump,supply drop, ie. reduced steady about 1-2oz per month....But I think it is OK if you direct feed more after back from trip...:lol:
