The third trimester insomnia was the worst for me! My legs, feet, and ankles also swole quite a bit. Good information and a realistic look at the third trimester!

Overall these are great tips. But I just wanted to point out that the cat litter is actually a myth, while cats can carry it, most indoor cats do not have it as they only get it from outside. You are more likely to get toxoplasmosis from dirt, so if anything, you should avoid gardening.
