Helpful comments please! My boyfriend isn't very patient with our 7 week old daughter. He gets so frustrated with her crying. Every time she cries he brings her to me and says I dont know what she wants or what to do. There are times I need me time..like when I'm in the shower or when I'm trying to poop. He will pace outside the door or bring her in and try to hand her to me. He gets so stressed out. Are there any ways to help him without actually taking over? I tell him what she likes (sitting up, tummy time on your chest while patting her butt, ect.). I can tell she gets frustrated with him too and by the time I get her back she is pretty upset. He's trying hard with her. I've even heard him say that he thinks she hates him. Which isn't true. Any thing I could do or say to help?
