Witchymommy - my DD was in a Pavlik Harness from 7 weeks through to 5mths. Well done firstly on picking up the harness was not fitted correctly - that is just not good enough. I dressed DD in clothing that was generally a size bigger than what she would have been without the harness. I found seperates to be be good ie. t-shirt and leggings, dresses also work but I didn't really do a alot of dresses, romper suits also worked. On hotter days (and remember the Pavlik harness is like a layer of clothes so you have to be careful of not dressing too heavily) suits with no legs were perfect.

Breastfeeding I actually had no problems with but that was largely because my daughter was so small and light (born 5lb 14oz) she was easy to move around.

Feel free to ask any questions and I will try and help.
