Oh thank goodness You posted this thread! I've been worried I haven't been gaining enough! Since a few days ago I have upped the amount of eggs I eat in the morning to 2.5 (eating 5 between hubby and I), I add cheese (extra protein!) AND spinach to them (iron!) , and we started having two sausage patties each with the eggs. So I start out nice and full of protein. I also stocked up on a bunch of chicken because it's cheap protein, and I've been having about .5 lb of chicken per meal for the last couple of days.. And I feel much better now. My baby bump is even sort of there now that I'm staying full of protein.
I still haven't gained more than a few pounds, but adding more protein to my diet has made me feel a lot better. In the second trimester they're building bones and muscles, according to Nina Planck (author of Real Food for Mother and Baby), so the most important nutrients are protein and calcium.
Right now I've got some homemade chicken bone broth stewing in the crockpot to add to a sausage and pea soup I'm making tonight. Homemade bone broth has many many more nutrients in it than store bought broth, including tons of calcium (which store bought broth has none of, indicating it isn't bone broth). It's easy to make in a crockpot with leftover veggie pieces and leftover chicken bones. I don't have a compost, so I save all my broccoli stalks/carrot tops/pepper seeds and stems/asparagus butts/ onion tops/etc in a freezer bag, then I save the bones and juices from the rotisserie chickens we sometimes buy at the store when we don't want to cook. When I want stock, I throw the whole chicken and it's juices into the crockpot with as many leftover veggie parts that will fit, fill it with water, and cook on low for 18-24 hours. It makes the house smell DELICIOUS. One it's done, you just strain out the veggies and you can store it in mason jars in the fridge. I usually use all of mine at once though, because I have a smaller (4 quart?) crockpot, so it makes enough for me to add to one pot of soup/stew (I always make enough soup/stew to have a few days of leftovers).
Sorry that message was so long.. I've been obsessing over my lack of weight gain for the last 5 days so I am glad to know others are experiencing the same.
In case you're curious about my status: I'm Kate, I spend every miraculous day with my darling soul mate JB and we are expecting our first baby (boy!) ...
