I did BLW with dd1 as she was a spoon refuser. Loved it, worked a charm. Yes it's messy but I found it a lot of fun and loved taking loads of photos. I found it a relief that the food wasn't about filling her tummy at all as the milk was still doing that. She's a great eater now too at nearly 3, eats a big variety of meals.
Doing BLW again with dd2, 8 months, she seems to really enjoy it so far but loves her milk. I love watching her take bites and chew and swallow, it's so cute and I'm proud of her for learning to do that so young. She's bf whereas her sister was ff so she has more milk feeds in a day than her sis did, who guzzled enormous bottles, but I'm still finding it do-able.
I'm not smug and do not evangelise, don't find the mess that much of a problem, have never found mealtimes that slow and have managed to mostly give my girls healthy food.
I can understand why people don't want to do BLW though and I never recommend it now, as I've had too many situations where, after chatting a bit about weaning and I say I'm doing BLW, a friend decides to try their spoon-fed baby with a big floret of broccoli and then when said baby gags spectacularly on the broccoli and makes a big mess by mushing it into their t-shirt and throwing it onto the floor, I'm then the evil cow who tried to kill their baby and has caused a big clean up operation
Just the other day dd2's gagging was causing a friend who has his own little kiddies to go v pale and terrified worried looking. So no, I don't recommend it, don't want to be held responsible!
