I can't give you an LC recommendation, but I wanted to reassure you that starting solids may not be that stressful. Why don't you check out the BLS area? If you just offer baby bits of what you are eating, you may find he's happy to take some or would rather wait. Your bm will most likely be enough for him until 7 mths.

I started my DD on BLS at 6 mths and it took her about a month to be interested. She was a voracious eater after that and still is!
