Would be grateful for some advice. Working 4 days a week. Breastfeeding 10 month old at night - every 2 hours or so. Do not have time to pump at work so boobs quite full by 5. Maternity bras now loose around the back and looking a little worn. Was wondering whether I could buy underwired ones to wear during the day. Is this ok? Will my boobs change size again when I stop?
