...yes! Mine is now 8 months and sounds very similar. He doesn't like to sit on his own (with toys) and still isn't much into eating. He often prefers to "stand up" in the bath (cries when I try to lie him down or make him sit). He shows no interest in crawling. When I put him into his playpen he only wants to "stand" by holding onto the edges (he can't stand unaided yet). He only sits alone 'happily' in a semi-broken hammock-seat as he likes to fiddle with it. All a bit tricky when relatives tell you not to let him put weight on his legs (especially when he was younger). Argh!
