The baby won't be affected. They won't understand. You're not an awful mum at all. I too am going through something that has completely destroyed my life this isn't about me it's about you. Life happens things happen and sometimes you need to cry. You are allowed to show your emotions. It could be generational. Maybe speaking to someone may help but only reading you have no one to talk too.. this is not me suggesting you should. I hope you are ok and Im sorry to hear you are having a hard time.
Cut yourself some slack, if things are awful and all you did was cry in front of your little one - you’re doing an amazing job of holding it together. Your baby won’t understand what’s happened and honestly wouldn’t pay too much attention to it. What you need to think of is how to get help, and not waste your energy on thinking you’re a bad mum. You’re a human being first of all, and allowed to feel what you feel. Your baby will be absolutely fine with a mum like that. Hope things take turn for the better for you ❤️
Oh sweetheart, sending you all the love ❤️ you are in no way traumatising your little one for being human and crying!! You’re doing a wonderful job ❤️
