I know washing your babies bottom does not invalidate wudu, from what I read on this website. From my understanding washing urine and feces of your baby does not invalidate wudu. Does this apply until they are able to wash themselves? Is there an age that washing your child does invalidate your wudu? Does touching their private parts in order to clean them invalidate wudu?

Assalamu alaikum wa rahmatullah,
No, this does not invalidate wudu at all, Please see the following answer:
