I have just bought a trampoline for my DS5 birthday and he's mad over it and always asks me to get on. I am 23 weeks and do get on but mostly just sit cross legged so that he can bounce me. However, I have had a little bounce, in the traditional way, but only for a very short time. Am I correct to think I'm round the twist and should not to it at all? I read somewhere on a thread about it affecting the placenta. Any clues? (I know I'm old enough to know better but sometimes I just need telling.) Thanks in advance.
