5 months is:
First tooth poking through, trying to chew on everything and everyone that comes closes enough,
Rolling over both ways and wanting to show it all the time, try to change a nappy....
Crawling forward then getting so excited that he goes backwards again,
Sitting at the table in his high chair and eating three solid meals a day,
Waking up once a night for a feed,
First swimming lesson,
Having a smile for everyone.
