Seven months is solidly more than half a year. It just seems like Hal is so old now, even though he really is still a little baby. :) That being said, he is eating solids, has some teeth and showing some signs that he's getting ready to crawl. He is definitely growing up, which is the whole point, and is so fun to watch! :)
We are doing baby led weaning/feeding with him so he's been feeding himself a variety of foods and he's gotten really good at using a spoon! Don't get me wrong, he's still a baby so he obviously makes a huge mess and doesn't eat a huge amount. We're letting him experiment and learn and he loves being able to eat with us at meal times!
