Over the past week or so, my son (who has always been prone to vomiting) has woken up after an hour or two and thrown up. Once this has happened, he's perfectly fine, goes back to sleep with no difficulty etc and that's the last we hear of him til morning. I'm positive it isn't a bug as he's totally fine during the day, eats and drinks with gusto.
He has only the lightest of snacks in the evening and a 6 oz bottle of milk before bed - as has been our routine for months now. I just cannot fathom what's suddenly causing this.
Has anyone had a similar experience? Advice/thoughts gratefully received.
