Stress after birth

You are not being sensitive. It is them who are insensitive annoying twats. 3 days?? Are you kidding me? I couldn't walk without extreme pain for more than a week. If they last time gave birth and can ride bicycle the nxt day then that's their grandmother's problem. Maybe try to be sarcastic with them "nicely." For your husband, you really need to talk to him heart to heart. Tell him how good things were when you both jz got married and that you need him to build you up back, to be in this, together, like a team. Together, always. In good or bad times. All the very best. You got this!
