Hi R_B, as a student midwife I can reassure you (and any other worriers) that we don't even start to think about importance of position until around 34/35 weeks (with the hope that all heads will be facing down by around 36 weeks). I would go so far as to say that I would be amazed if your baby was head down at 22 weeks. Most tend to lie transverse or head up during earlier pregnancy. Don't panic - you have plenty of time. And for all those further on who are beginning to think about wanting to turn their baby best advice is not to slouch on sofas/chairs. Especially important for those posterior babies. If you do need sofa time lie on it (preferably on your left but don't worry too much about this.) Otherwise birth balls, leaning slightly forward when sitting, eg turn your dining chair round and sit cowboy style. And yes there is always the traditional floor scrubbing! Ellen
