So I have been feeding DS1 mashed sweet potato and squash that I made (I forgot about the "need" to puree it)...does it really matter if it isn't pureed (so water added to make it a smoother consistency)? He has easily eaten a few tbsp of the mashed from day one, so is there any reason to puree that I am missing? (other than making it easier to swallow?) He does have strong mouth muscles and the other day quickly drank 3.5oz from a straw sippy cup (he had been fighting drinking from the bottle yet again...)
