help! my baby isn't pooping

My lo started solids, he ate poi (taro & water) on Thursday and he's hasn't pooped in two days. He usually poops once or twice a day. I have given him peaches and some prune juice but nothing. He seems like a happy boy but he is going onto day 3 with no poop. What should I do? We just moved to a new state and we don't have a dr yet.
