I saw that headline and thought, ouch, that's a very bad headline. It's making a very distinct comparison, and lays the blame on parents going for IVF.
In reality, the adoption process is pretty harrowing and lengthy, just as the IVF process is. But for different reasons.
Adoption rarely involves a healthy baby. It almost always involves a child who has been damaged or traumatised. Sometimes, it involves a sibling group which are even harder to place.
Adoption is the last resort in this country, when "nothing else will do" (Family Court). Support for parents in difficulties, such as Sure Start, has been cut to the bone. Post-adoption support is very patchy.
To focus on IVF being the reason why adoption rates have fallen is beyond ridiculous.
