hope this won't be massively controversial, but i got mega-stressed by this whole blw milarky.
i was massively pro-blw when i started weaning dd and she was an exclusively blw babe until about 9 months. she just couldn't get the volume of food that she needed. i was breastfeeding her as much as possible but she dropped way behind her peers on the weight scale. i was really stressed about it until i just decided that i would try mash and spoon feed her. at the end of the meal i'd give her stuff to throw around the kitchen. she's been great ever since.
i feel disappointed that i couldn't exclusively blw but she plays with food rather than eats it.
so if yours is like my dd, don't sweat it if blw isn't the way to go. it's not the be-all and end-all.
