Lissy your story about your cat brought me to tears. It's crazy how powerful animals can be in our life. I have a cat and a dog and know when I'm having a tough day they bring me joy. My cat (who is not the most affectionate thing) actually got in bed with me last night and slept with her head on my tummy. I didn't want to move I was in shock! The thought of losing her or our dog is something I dont want to think about. I think it's a good idea for you to start a blog/novel etc regarding your kitten. If it helps you express your feelings and maybe bring joy to someone elses life then go for it.
The book recommended to me with the Healthy Baby Code by Chris Kresser - are you comfortable giving me your email I will send you the PDF's. I also just started reading a blog by Arsy Vartanian called Rubies & Radishes. She is paleo and just had a bub and talks about nutrition for that too. I've got heaps of paleo bloggers I read but another good one is cavegirleats.com this one is more on a nutritional level as well. I eat a bit of dairy too (full fat organic) and cheese when I can stomach it but no grains (expect for yesterday when all I could stomach was white toast!!!). I just bought the Practical Paleo and Gather cookbooks too!
Oh and don't worry about the weight gain - I've gained 6kgs since beginning of last year. It's just so hard to maintain or lose when you're pumped full of hormones, plus the emotional side of it. I actually caved last week & bought a size bigger jeans and they are sooooo comfortable!!!
