SD is almost always a positional issue rather than an inherant problem with mum's pelvis or due to big baby/wide shoulders. Babies are born weighing >4kg every day and don't get stuck and babies weighing <3kg are born and do get stuck.

If baby was not posterior or in another irregular presenting position, you were not induced, had been active during your early labour, were pushing in hands and knees, on a birthing stool or in a supported squat and had not had an epidural then you might want to consider a section, since you gave the baby every chance to be in a good position and offered as wide a gap as possible for bubs to come through.

If you had been laid on your back for much of early labour and/or were pushing in a reclined or semi-reclined position, had had an epidural, or were being induced or augmented then it's likely the intervention contributed to the dystocia and avoiding these factors would make it very unlikely to happen again.
