You guys prob need to talk about it a work out a plan that works for both of you. Once my husband whent back to work Friday and Sat nights he dealt with both babies and on sat he sleeps in and sun i do. Try to work something out that works for both, maybe your partner will be more understanding if you talk about it at a calm time of the day, not the middle of the night, and if she knows what is expected of her and how to do it. Try not to attack her, you are in this baby thing together.
