I have back problems and big babies, so I can totally sympathize! I have to say, they Ergo is the only carrier I can use anymore that takes the weight off of my back enough so that I can get some stuff done and DS falls asleep in it sometimes too. I've even done yard work, like blowing the leaves with him in it and it worked great. I found the swing to be worthless this time, DS hated it. DD loved her swing and napped in it everyday. DS loved the high chair at 4 months, he could see me cooking and doing stuff in the kitchen and it gave my arms a break.
As for the overweight baby thing - I can't see how a baby that is either exclusively breastfed with no other source of calories could be overweight. DD was EBF and was a BIG baby. She was over 20 pounds around 3.5-4 months. Now at 4 years old, I worry she is too skinny, she has no fat on her at all. She is a tall, thin bean pole, lol. DS is formula fed since 6 weeks old, and even than, unless you are adding cereal to bottles or forcing them to eat when they aren't hungry, which wouldn't be too fun for anyone, I can't see how they would be "overweight". DS is big also, and has been since birth, just like DD. He's crawling now and I've noticed his weight starting to thin out a bit already, though his height is still on the fast track
