The charts below were compiled by another momo mom, thank you Megan!  She has a slightly different collection of data (from two different momo communities) so the sample sizes are different and the stats a bit different.   

47% of MoMos were delivered at 32 weeks followed by 10% at 30 and 33 weeks and 9% at 31 weeks.  4% were at 34 weeks and 27 weeks, and 6% at 28 weeks.  26 weeks and 29 weeks were 3% each and 23 weeks and 25 weeks were 2% each.

57% on Inpatient MoMo moms (66/116) made it to their scheduled delivery date.

43% of Inpatient MoMo moms (50/116) delivered by emergency c-section.  24% of emergency deliveries were at 30 weeks followed by 18% at 31 weeks and 14% at 28 weeks.  12% of emergency deliveries were at 32 weeks, 10% at 27 weeks, and 8% at 29 weeks.  4% of emergency deliveries were at both 23 weeks and 25 weeks, and 6% were at 26 weeks.

 This chart lists when MoMo moms chose to go inpatient.  38% started inpatient at 24 weeks followed by 26% at 28 weeks and 12% at 26 weeks. 27 weeks and 23 weeks were 10% and 8% respectively.
