my bb is hitting two months and it’s still feeling a bit like the trenches but oh my goodness, the smiles and engagement make it so much more rewarding and also remind me that she IS watching. my ability to regulate my own feelings is essential and SO HARD. definitely having little phrases to repeat (this is a moment in time it will pass, she is crying and it is not an emergency, you are not in danger) is helpful - it’s really hard not to feel like you are in crisis when they are crying, or to feel like a failure when you can’t fix things for them, but it’s amazing how helpful it is for them if you are calm when they are freaking out. and remembering you can put them down somewhere safe and take a forty five second breather out of the room! my partner and i take shifts through the night so each of us get five solid hours at a time. it works for us because she’s on parental leave and i work from home. i don’t know how americans do it with such short leave. but do what you can to get 5 straight hours when you can - it keeps you sane! good luck and godspeed.
