4 1/2 months and learning

I just don't know what to do anymore, he is changing before my very eyes.
He has been rolling over from back to front since 4 months, however at the time he absolutely hated  being on his tummy for a time and he just cried and fussed until he was flipped back over. Now at 4 1/2 months he deals with being on his tummy and he shimmys towards the toys I put in front of him, haha. Recently he has mastered spitting up on me almost everytime I have a new change of clothes on, or right before we go out wether it be grocery shopping, running a simple errand or right before church. Both my son and I are learning solids, for as more than most of you mommys know, it is a super messy job. He likes to stick his fingers in his mouth while having food in it and then rub his hands all over his face. Good times. :)
We got to do a few new experiences with Josiah these past couple months and he has been doing better than I thought he would. First was the volcanoes game on the 3rd of July with the fireworks. He did fairly well for the nearly the whole game, but we ended up having to go home right before the fireworks, he was starting to fuss and having a crying baby during the firework show would have been a little difficult.

Just yesterday my husband and I got back from camping with a few friends, in a tent with Josiah. The weather was beautiful, the sun was finally out for me to get the vitamin D that I wanted(a little too much I might add), and Ben and I needed the time away from the busy city for awhile. It was wonderful, Josiah did so well sleeping in the tent, it was then I realized that he sleeps overnight on his tummy. I flipped him over a couple times cause it was freaking me out a bit but he just kept flipping back over to sleep. So anyway thats most of it, I havent been able to keep up on this for a little while because our laptop was shipped to Texas to be fixed. But I'm back in the game!
