Ok, I am not SN certified and have no experience with any special needs, but I am having a hard time contacting area techs who are. I have a friend whose son has severe cerebral palsy and recently had hip surgery and was given a Hippo to use until the long-leg broomstick cast comes off. He is 15-months old, but about the size of a typical 9 mo. I don't know exact stats. He has little/no head control, no trunk control, etc. They were looking at ordering a Hippo, but are worried that the 35 lb RF limit might not be the best option. He shouldn't need the openness that the Hippo has once the casts comes off, so my questions are 1) which regularly available seats (if any) might be good options for them to look at, 2) if not a regularly available seat, are there any SN seats that might last them longer RF, 3) will insurance cover a non-SN as they would a SN seat? I don't want to overstep my certification, but also don't want them to go with a less-ideal option just because of unanswered voicemails. TIA
