Be cute and loving. She'll eat it up and you'll get browny points. I personally love it when my husband rubs my tummy and tells me I'm beautiful. A big thing for me is when he makes me feel sexy, it automatically puts me in a great mood and I just wanna love on him. When he does those things, I can't help but be happy so we bipass all of my mood swings. Lol
At least that's how I do it lol & also be silly, say, "babe, I'm gonna spoon the **** outta you!" Guarenteed to make her laugh
Don't argue, and don't get loud. When she says she's hungry, ask her what she wants & make it for her or go get it for her. Don't ignore her craving. Every night when you guys are laying down for bed, talk to her belly, it will make her happy, I don't know why but it works. Offer a foot massage or a back rub each night, cuddle with her, spoon her & hold her belly, all that kind of stuff will help
