My lo is 9 months. She's gorgeous and fun and full of life. But I'm finding maternity leave / bring main carer really hard. She doesn't sleep well which I know impacts on how I'm feeling- and I feel a failure because I haven't managed to get her sleeping well. She's breastfed which has to started to make me feel trapped and sometimes frustrated. Because we're so tired, my relationship with my husband isn't what it was- sometimes I'd cheerfully punch him in the face and really he's done nothing wrong. Does anyone else feel this way?
