Autumn - we're in the same boat
I do a modified version of P2. I love the planning aspect of SBD, and continued with it after we found out we were expecting. I have my morning meal, a snack around 10, lunch, another snack around 3 and dinner....I usually end up having a snack after dinner as well.
I decided to forgo the Splenda during the pregnancy and while I was lactating, so I avoid anything with artificial sweeteners (sugar free jello, sugar free pudding, sugar free fudge pops, sugar free drink mixes, sugar free yogurt, etc.)
I try to have protein with every meal and snack and probably get more fruit than is recommended on SBD P2. I still try to get the recommended 4.5 cups of veggies as well.
Also, I've upped my dairy intake. I have a cup of yogurt with breakfast (I use organic, natural yogurts - full fat) and a cup of 1% milk with both lunch and dinner. I'm kind of a milk addict though.
Carbs are very important to developing babies and I try to make sure that each meal has at least 1 serving of whole grains - whether it be brown rice with dinner or a slice of ww toast with breakfast.
