So the itch to start shopping has been getting pretty strong... What I am wondering about is clothing sizes. I know it varies baby to baby, but as for buying ahead of time or registering, are the "monthly" sizes relatively true to age? Meaning, if the baby is born in February, if I buy summer-y outfits in the 6 month size are they likely to fit? And fall outfits in 9 month... etc. I know the smart thing to do would be to just not purchase those type of outfits ahead of time but they are JUST SO CUTE! Just wondering, thanks for any help!
