DD (7 months) has in the last week started to wake around 5.30am with a huge bowel movement. By this hour there's no chance of her settling after being changed so the whole day gets thrown out.
She's always been very regular, but used at least to wait until around 10am for her first purge (another normally following around lunchtime). Her early morning thing seems to have begun around the same time as us introducing protein (chicken or fish) at her lunch feed. She still has fruit and rice for her tea, as always.
Any ideas on whether food changes could help this unwelcome pattern?
