I'm female, and was 33 years old when I started this job...I was married and had a teenaged son at the time. To your question of how it was to go to the academy with kids; I was very lucky in that my son was big enough to do alot of things for himself and both he and my husband helped me out by doing all of the household chores including cooking. I owe a lot to my husband, he has always supported me even though he didn't want me in this line of work.
I am all for women's rights, including the right to bear children (occasionally) and the right to have a reasonable accomodation in the work place while incapacitated by the dreaded belly disease. There are just too many reasons to state why I would not advise trying to start a career in law enforcement at the same time as you are adding to your family. p.s. Lest you think me a sexist, I also think men should refrain from the family additions during the first year or two on the job as well. If they can't I damn sure don't think they should ask for six weeks off right in the middle of FTO to bond with their kidlets.
It would be darn near impossible, not to mention unsafe for you and your fetus to get through six months of an academy and another 2-6 months of Field Training. In my not so humble opinion, if you choose to get pregnant while applying for a job, you are just wasting the Department's (and your own) time.
You aren't that old, why not pick one or the other to do now and then commence with the other later when things aren't so hectic?
"It's snowing still," said Eeyore gloomily. "So it is." "And freezing." "Is it?" "Yes," said Eeyore. "However," he said, brightening up a little, "we haven't had an earthquake lately."
