So cute! It's wonderful having friends with children so close in age!! They will grow up being friends forever.

I find that boys are often bigger then girls and develop physical skills faster. Not always, but often it seems. My son was always in the 95th precentile and my little girl is in the 35th. He definitely rolled early and was sitting up by 5 months and she's not even close. I've had so many people say Girls talk earlier and mature faster but who knows!

My mind is blown that your son is outgrowing his size 4 diapers! How much does he weigh? I bought a pack of 4s today because we had a terrible blowout in a size 3 this morning, and the 4s are way too big still. They're long as heck! My baby's over 16 lbs, in size 6-9 month and some 12 month clothing as well. I packed the size 4s away in the closet and we'll stick to 3s for another month or two.

That's adorable! ❤️

My sister in law had a baby boy 7 weeks before Marley was born.

Then we have a family friend that has a baby boy that's 3 weeks older than Marley.

And my very best friend has a baby girl that's exactly 6 months older.

It's baby season! Lol
