Did I order the right size Baby Merlin?

Ok ya'll convinced me to get the Baby Merlin Sleep Suit for my sleep deprived son. Now I'm wondering if I ordered the right size? He's 4 months and 15lbs. I would like for him to use it at least 2 more months. I ordered the 3 to 6 month size which says it's for up to 18lbs. Wondering, for those who use one, if this is accurate?

My LO is 15lbs, 3.5 mos, and the 3-6 still has plenty of room in it.

Perfect! Thanks
