I've been going by both. I'll say weeks unless it's close to his actual month-day then I'll say his age in months. I'll probably stop counting weeks when's he's 4 months old just because.
DH thought we missed his 1 month pictures when he was 4 weeks. I reminded him it's on his birth date otherwise he'd be 12 months before his actual first birthday. I plan on using both months and weeks until 6 months.
I've noticed with my son and now the baby that I use weeks up to about 3 months of age, and months up to about 18 months of age.. after that, it's too much math for most people
I was just thinking about this! LO will be 10 weeks tomorrow and that's when I will start saying his age in months. I guess I have something against the double digits! For monthly photos, I go by date so that he 1 year will actually be his 1 year.
For me, it just depends on who I'm talking to. I use weeks with other moms of little ones and months with anyone else. Months are easier for most people.
I use weeks until it's close to the month birthday then I'll say "he'll be 2 months on Thursday" etc. I go by his actual birth date not by weeks. I'm not sure when I'll stop using weeks but maybe after 3 months?
Re: Baby's age. Do you go by weeks or months?

He had to walk away (to laugh) because the woman looked so perplexed as to why someone would just say the year at that point.
