Just that really, dc2 has no other traits except really poor sleep and language developing well etc but dd1 regressed so its hard not to worry. Dd2 is twenty months. She has over lapping toes which may be relevant but she walked early (before ten months) so they don't seem to affect her. I think she is toe walking since having laminate floor rather than carpetweed living room, certainly its since this that I have noticed.
Would you worry/do anything? Dd1 never toe walked but I know it can be associated with sensory issues.
