Liam amazing fifth month!

The past two months have been very busy for Liam in the learning and developing department. I will just focus on his fifth month because I have already talked about the fourth month. We have not yet taken him to the doctor for his six month check up, but he will be six months on the 8th of this month! Time has gone by so quick I wish the pregnancy would have done the same.
I got Paul to get on the scale with him and we are estimating his weight to be about 16lbs. 4 ounces.
He has gotten two of his middle bottom teeth and it really shows by all the drooling bitting and sucking he does twenty four seven.
He rolls constantly both from front to back and back to front. He actually prefers to sleep on his tummy now.
He has gotten up on all fours once.
He has a tendency to scoot himself backwards with his arms.
He sleeps through the night in his own bed.
He is now not only eating rice cereal but peas which he does not really care for, sweet potatoes, squash and pears.
I have also given him diluted apple juice to help work these new foods through his system.
He is still an excellent breast feeder which I love!
He is saying ba ba, da da and ma ma.
I just got him a walker and he is really good at pushing himself backwards with his toes.
He also got sick for the first time well i consider it the first real time of being sick, yesterday he got hit with the stomache bug and threw up every five min for about three hours. It was so heart breaking for me to watch him gagging and heaving into the bowl. All he wanted to do was snuggle to me and I would have to push his face over the bowl as to not get it all over. And after his little head would just hang over the bowl and he would start to fall asleep from all the work it took. I cried everytime! My sister brought me some pedialyte for him and he was all pale and clammy and he still being the sweet heart he is was giving her smiles all over the place she felt so bad too seeing how sick he looked but still smiling.
