No, no particular difference. Still waking about once a night at 8mo.
There is some evidence that EBF babies who start food at about 4mo tend to be better sleepers in the long run compared to those who start at 6mo however (this was based on a very large randomized control trial, by the way). The average difference between the two groups was small, but the group who started early were a lot less likely to be terrible sleepers as the months went on.
I suspect that starting small amounts of food subtly changes the parenting "style" by making mothers feel more confident about not breastfeeding every single time the baby wakes up ("She had some food this evening, she can't be hungry yet!"), which may reduce the chance that a baby develops a strong "suck to sleep" association.
Also, if you are planning on night weaning/sleep training, IMO sleep training is far more likely to work once the baby is eating a reasonable amount of food, in the case of a EBF-as long as they are overwhelmingly dependent on breastmilk, very few mothers are going to have the nerve to deny the breast when the baby cries, and you can't start giving a EBF baby water until they are taking some food, but if you cannot offer water in the night then you have no way to rehydrate them without the breast, so again, you will just end up caving and getting a breast out, and so night weaning/sleep training will probably simply not "work." So weaning is "helpful" as a step that will enable night weaning/sleep training, if you were planning on doing those things. On the other hand, if you were not planning on doing night weaning/sleep training, food will make no differenceI don't think the food in and of itself has much effect.
