With DS1 morning sickness started at 6 weeks and continued till 24 weeks. It had a few better patches and a few worse patches, the last couple of weeks were pretty mild just spewing every few days.
With this bub the morning sickness at 5.5 weeks but was much much milder than the first time, only a couple of spews in total and mostly just general queasiness which could be managed by small frequent meals, it's also been pretty well gone for the last week or so (probably ended around 12 weeks).
