My 6 month old DD has always been an amazing sleeper (sorry; any consolation, DC1 was a nightmare and still is at 4 years) ..... until I started weaning her 3 weeks ago. All gradual, all fruit and veg etc but for some reason, she now wakes up loads in the night, is more sick, has been constipated etc. I plan to ask HV for advice but am more interested in MNers really because my experience of HV advice not great really. There doesn't seem a pattern with what she eats and how she sleeps as she does still have the odd good night.
