Let baby cry non stop?

My baby is 7 weeks old. My hubby insist to let the baby cry non stop when the baby is cranky. Meaning diaper already change also feed the baby. My baby like to be hold, pat and walk around so she could fall aslp easily. My hubby said want to train the baby from young but I cant bear to see her keep crying non stop till cough and choke. My heart break but i cant do anything when I pumping my milk and my hubby is the one looking after her during this period of 30 to 45 mins. It is ok to let baby keep crying till she stop? I really afraid it will hurt her lungs for keep crying so badly :( Appreciate any kind advices. Thank you
