2-element clusters

Sonority difference: 2

Note. If you have not confirmed that the child is treating /sm/ and /sn/ like true clusters i.e., /bl/ and /fl/, in relation to which of the two consonant segments the cluster is reduced to (C1 or C2); do not target them. This is because /sm/ and /sn/ may treated within the child's system like adjuncts (/sp, st, sk/) which can behave differently to true clusters and produce mixed results if targeted in therapy (see Gierut 1999, Gierut and Champion 2001, Storkel 2018b)
