I just delivered my second girl on september 25. My first daughter was just 4 months old when I conceived again (when I still was recuperating from the first pregnancy). I was still in pain (delivered a big baby- 10 lbs, 14 oz..yeah) and I was still adjusting to being a new mom. So pretty much the last two years have been a roller coaster for me! It is do-able though and of course you know as a mother- totally worth it. So daughter #1 is 1 years old now and the new baby is 1 1/2 months old.
It is crazy around here! I am so exhausted some days and yes sometimes it's hard to get something to eat myself as I'm feeding two little ones also. While pregnant and taking care of my first daughter, I just really did try to focus on just me and my daughters. I made sure I was eating well for the one living inside me and I made sure my sugars were under control.
I was in pretty good control for both pregnancies, though I still delivered two big babies for some reason. The second was smaller though. She was 9 lbs, 6 oz. I did use an insulin pump for the second pregnancy which allowed even better control so some advice for you is maybe look into that if you're not already on an insulin pump.
I guess I got a little off track here, but what I meant to say is, just focus on eating well and staying in control for your baby and don't stress yourself out. Try to relax whenever you get a chance. Ask people for help if you have those people available to you. Take it day by day. Now I'm realizing maybe I don't even have that much advice or words of wisdom as I'm new to mother hood also but maybe it's just nice to hear from someone that went through something similar as you are...
