I am after some advice. Since the birth of my son who is now 13 weeks I have had the odd day & sometimes a couple of days ina row where I cry over everything, feel like I'm a rubbish Mummy & wonder what the hell have I let myself in for. Then I can go for days feeling fine loving being a Mummy, happy etc .... I do however tend to worry constantly about my son, is he eating enough, he breathes funny ....etc almost obsessive on whether he is ok?? Is that a sign of PND?
