My baby is 3 months, but is already fitting in 6 month clothes. Should I size up to the medium or stick with the small?

I would if your baby is taller than average. We use the M size and have since my little one was 4 months. They work great! She’s almost 7 months now and they still fit her well. She’s in the 97 percentile for height.

For a baby that’s 28.5 inches long which size is better?

I bought M. My baby is 10 month and 28”, we are currently using them and she still has room

My baby only gains a little over a pound a month and is currently 11.7 and 23.5 in long at 4 months. Should I get small or medium?

When I got mine my baby was 4-5 months old & weighed 13 lbs and was around 24 inches long. I got her medium. She is 6 months old now weighs 17lbs 27.5 inches long & she still has room. I liked hers being a little better because she still has room to move around & likes to have the “freedom” but if your kiddo likes to be a little bit more “snuggled” I would get small.

Does it zip from feet to head for night diaper change?

It zippers up to the head and down to the feet and zip is covered with fabric
