@daniel1986 My husband's cousin has six kids like GBBBBB
My husband's neighbors have 8: GBBBBBBB. in my husband's family he and his siblings were: BGBGGGG.
@ajewelinhiscrown If my husband made these kinds of comments then I would tell him to keep his comments to himself unless he wants me to come down and comment on his work too (he also works from home). It absolutely would not fly.
@nart Keep track of the individual acts of favoritism and share them with him in private every time. Make it a big deal. Maybe note the other kids' reactions and share that with him too.
