Weeks is how you’ve done it, quite literally the exact amount of weeks after the birth. Months are to the date they are born. There are more than four weeks in a month hence why 4 weeks and 1 month milestones done line up x
Weeks = day they were born Months = date they were born So my LO was born 14th July... on 14th Sept she's 2 months old OR 8 weeks 6 days
My little girl was 2 months on the 3rd. My mother in law put a Facebook status at 4 weeks saying she was a month and I said to my partner she's not a month
Every Sunday my boy is a week older but on the 7th of each month he's a month older, so he's just turned 2 months but the day after he was 9 weeks, I do his milestone photos on the date rather than the day x
My milestone cards went 4 weeks, 6 weeks and then 2 months. I have counted my little boys 2 months mark from the date he was born which ended up being a day before he turned 9 weeks. I will now do the milestone months on the 6th of every month x
