M.S.
Hi, you are doing GREAT...Your baby just turned 1 for goodness sake. There are LOTS of breasfed babies out there, and sometimes thats all they have, and they poop just fine! hahahaha!!! My son just turned 2 and he WILL NOT eat any fruits or veggies (except corn and applesauce)...so guess what, I still buy some carrots and peaches or whatever in baby food just so he gets at least a couple a week!!! He is more of a meat/potato kid. He is a big boy for 2 - 40 lbs.! I keep trying and trying, (and bribing)!!! His staples are breads, pastas, yogurt, cheese...and pretty much anything in those families (i.e. pancakes, mac & cheese, pizza, crackers, toast), etc., etc.
Again, just keep trying (and see if a bribe will work from time to time), and if you need to "supplement", then you do what you have to do!!! Totally normal!!!
The best of luck to you and your family!
