My 18wk old requires constant holding and entertainment otherwise he cries so bad he struggles to breathe! I have bought lots of toys, a snug seat, bouncer chair, jumperoo, baby gym, musical mobile, but none of these work. He will cope with 5minutes or so in his gym or jumperoo if you are right beside him talking or singing to him before he begins hysterical screaming. He does not tolerate his pram or carseat either as he is not being held. Iam at the end of my tether as there is only so long you can sing nursery rhymes for without going mad. Any advice or suggestions?
