Just bathed my 3 children DS1 5.9 DS2 2.2 and DD 7 mths. When I rinsed the shampoo off DS1 hair i could see the nits in his hair. I am so shocked but I know most kids get them. Has anyone got a reccomendation on which treatment shampoo to buy. Also I presume that ALL bedding needs to be washed but is a 40 degree wash hot enough or should it be hotter... any advice/information will be VERY greatfully recieved. TIA
