Already in 6 month clothing 😭😭

My son has hit what seems to be his 8 week growth spurt and has been nonstop fussing and needing to comfort nurse. I went to put his little footie pajamas on tonight and wasn't able to get him in them, within a few days he has already grown out of his 3 month clothes and into his 6 month clothes!! I couldn't believe it, he just wore them a few days ago, I do laundry and bam!! Already up a size. I can't believe how fast my baby is growing 😭  my baby who won't even be two months until Wednesday and is in 6 month clothing... It's still sinking in and I'm still In mommy shock.
