I think it's time I CIO with DD who is 6 1/2 months but I'm a little concerned she's going to wake up my 2 year old. Did this happen with anyone else? I've let her go maybe 5-10 minutes but then my DH runs into her room because he's afraid she's going to wake other DD and because he can't sleep if she cries Chat Icon I'm more than ready to do it but it's my DH who can't stand it and then we end up fighting and either way I'm up all night. So do most toddlers sleep right through it or should I continue to let DH soothe her?
