My little one got his vaccinations on the 31st ever since then he has had 3 HARD poops, we tried the qtip trick, we tried waiting. Karo syrup initiate as recommended by ped. We gave him half of a teaspoon in a 4oz bottle. It's SLOOOWWLLYY working it's way out, and I mean SLOOOWWLLYY. I hope there aren't many pebbles left so he can get back to his normal poops. I'm currently awake at 5a.m. Because he passed another tiny pebble poop and it woke him up from pushing so hard.
