I have 6 month old twins who are literally the light of my life. They sleep through (most nights), have a good routine and we go to at least 3 baby groups a week. So far so good but I feel constantly tired, very weepy on certain days and I have no patience with them when they cry. Sometimes I have to bite my hand otherwise I fear I may hurt them. Sometimes i shout so loudly at them and they cry even more. The guilt I feel is terrible and it makes me want to punish myself in some way. DH knows how i feel but i think he is getting annoyed that i can't just pick myself up and get on with the task in hand (he's the eternal optimist type). I have no family near by and dh works away quite often so i don't know whether i am in need of a bit of a break or whether i have mild PND. Please, if you have any experiences or advice, help me.
