Nope, he's not too small for the Hotsling. I'm curious about what is going on with the MW, though. You shouldn't have to constatntly adjust it. The fabric not being spread out in the rings can cause it to slip, though. You want the edges of the fabric to be at the outer edges of the rings. After threading, find the two edges and pull them away from each other.
I know you are frustrated, and I do think it's a good idea to try and have different types of slings. But the MW really is a good sling once you leearn how to use it. Here are a few tips and links:http://www.friendlyvillage.com/lotso...ling/tips.htmlhttp://www.thebabywearer.com/article.../SRNewborn.htmhttp://www.zolowear.com/Wearing.aspx#2
Maya tips I keep handy to C&P:
1. Make sure the shoulder flap is open BEFORE you thread your sling. That means that if you wear your sling on the right shoulder, the edge of the open flap should be the bottom edge of your sling all the way across your back, and the inner edge coming up between you and the baby. If you wear it on the right shoulder, it should be the top edge all the way around. Otherwise, the body of the sling WILL be twisted, and twisted is not good.
2. Once the sling is threaded, find the outer edges of the fabric in the tail and pull them away from each other. You want the edges of the fabric to be the outer edges of the tail. The pocket will be on the front of the tail (facing out). That way when you need to adjust, you know the inner edge of the tail controls the top rail of the sling, and the outer edge of the tail controls the bottom rail.
3. Have the sling adjusted close to where you want it before you put the baby in, so that you mainly adjust the edges of the tail. Otherwise, you start with the baby really low and will likely pull the rings down instead of pulling the baby up.
4. Make sure the lowest point of the baby is no lower than your waist. If the baby is in a hip or T2T carry with feet out, make sure the fabric comes into the back of baby's knee so the thigh is up in a seated position, parallel to the floor, and the top edge is at least up to the armpits. The baby's butt should be slightly lower than the knees so they are really sitting down in the seat created by the fabric.
5. Before tightening, pull all the slack in the fabric around from your back and pin it to your side with the arm supporting the baby. Continue moving the slack over the baby so that by the time you actually pull the tail, all the slack is right up by the rings. Pull each section of the tail individually to tighten, and pull sidways. This will help you avoid pulling the rings down. This last tip (#5) is especially crucial in the hip or t2t carries with feet out.
