3 days shy of 6 months; he did go through a short phase of sleeping less well at around 5 months but it was very short lived, also he had no interest in solids before then. I have also read that when their liver is ready to process solid foods they will develop sweaty hands and feet, crazyguider posted it on here as her friend who is a paediatric nurse told her this; if it is true my son only got sweaty hands and feet a week before he was 6 months-before then his hands and feet were bone dry. I still don't think he was totally ready for solids when he did start them because he was extremely constipated for over a month, we did BLW and despite him having soft fruits every day, avoiding consitpating foods, and him having water and lactulose (was told to try this after everything else had failed) it made no difference whatsoever. My eldest had the same problem but was weaned much earlier xx
