Been on here a while but name changed in case this is outing.
So I genuinely like my MIL who is a lovely person. Tragically, she lost a DD as a baby to SIDS. Now DH and I have just had our first baby, a DD, who's about 4 months old. MIL often compares her to her own baby DD - things like "Oh, Sarah (not actual name) was just like that." The problem is it terrifies me, particularly if it's to do with sleeping (as the baby died in her sleep). I don't want to ask MIL to stop doing it - I get it, she's seeing things in our baby that remind her of her baby, and that's fine. But I find it really difficult to cope with.
Any advice, oh wise people of Mumsnet?
