Babies born to older mothers have a higher risk of special needs, it is harder to concieve after 35 and there are more likely to be complications with giving birth and pregnancy. It is far easier to give get pregnant and birth at 25 than 40.
Unfortunately women are under huge pressure to put off childbearing until their late thirties because its very hard to build a career after children. I feel that there should be more help for mothers returning to the workplace after children and stronger legistation to combat age discrimination. Ie apprenticeships should be open to mothers returning/ starting out in the work place as well as under 25s. I would like more help to allow mothers to have career breaks and return to the work place.
Surely its easier to change the attitudes of employers than basic biology. (Ie. its far easier to have a challenging career starting in your 40s than to start a family.
