Susan,,I was just about to say that besides having the children to fill a void in their lives,,it may also have been in Junes' mind that she " wouldn't be left out ".An unkind way of putting it,but she wasn't exactly mother material in the sense of the word,,and your own suggestion about the parents needs rather than those of the childs,rings true in some ways when at first nannies were hired to take the strain,,then as they got older,they were bundled off to boarding school.
No amount of money would have tempted me to send my children away.Even the odd weekends they stayed with my parents,I missed them,so I couldn't have subjected the children to be sent away for any length of time.
Junes first ECT therapy was before she adopted. This would have been held within the doctors notes,but whether it would have been required then as proof of background,etc,I don't know. Maybe today,,someone like June may not be a suitable candidate for adoption,,I don't know.
