vb, I just noticed in your ticker that your little man is only 2 months olds. That is definitely too early for food. But that is about the right age for a wonder week - this is a time of huge neurological development when babies seem to feed all the time. Not a lot is known about why, but it is believed that they need extra fat and nutrition from the milk to build up the brain. It can be really tiring, but the best thing to do is to feed more often. It usually passes within a couple of weeks. GL hun, I hope you last that long!! (and FWIW, my second baby was much harder too. But he's much easier now LOL!!)
My neighbours 8 week old has just done this!!! He is formula fed and went from 4 hourly feeds to 2 hourly feeds for a week. Hang in there I bet he is back to normal very soon.

BTW - My second was way harder than my first and my third is a breeze
