K.E.
It is okay to have tuna and turkey....not all the time, but it is okay. I had both and my daughter is perfectly fine. I also have friends who craved and ate hot dogs and drank Mountain Dew the entire time and their children are fine. There are so many ridiculous "rules". Just eat healthy and in moderation and everything will be fine! I always packed a fruit, veggie and some cheese in my lunch. I usually packed leftovers of what we had for dinner the night before. If you like tuna salad, try making chicken salad instead and if you like deli meats, try grilling them or toasting them so that they will be cooked and bacteria is no longer a possibility. Pasta salad, PB&J and Low Sodium/Healthy Choice soups can also be quick and easy without being too unhealthy.
Hope this helps! Think about our mothers and all the "rules" that didn't exist when they were pregnant. I remember telling my mom some of the "rules" that I had read on the internet and her laughing at how ridiculous they all sounded. I gained 18 lbs and had a healthy 7 lb 7 oz baby. I lost all my weight within a week of her birth. Eat smart, but don't stress over the small stuff!
