I have two otherwise very nice SILs and MIL. Although they're very set in their ways!
DD was born 5 days ago. After the loss of DD1, then DD2, then DS2. All neonatal deaths. I have a lovely DS as well as DD so we are now done.
Both SILs and MIL are really not best pleased with what I'm doing. They are fine otherwise and very supportive but they are making comments and I don't know how to answer 
DD is co-sleeping with me, in DS's (double) bed. DH is in our room. They say this set up is all wrong! DS is going to get too use to me and DD being there, this is a very very bad idea. I said it's working lovely for now, DS is autistic and he has taken very well to all this, I think us sleeping together plus a huge part. SIL said NO, not my kids. Could never be me! Other SIL just nodded her head. MIL says 'well, you'll regret it'.
They also know how much I've spent on my pram and MIL thinks 'I've got more money than sense, but little of both'
They are most annoyed about the breastfeeding, all of them think it's absolutely not okay beyond 12 months. DS was breastfed until age 3... and still is secretly every now and then! If he's sad etc and it's bed time
There are other little comments too. I feel so sad. I try not to put myself in a position where the answer to a question can be picked apart, but it's hard going.
How do you handle these questions and negativity? It sounds ridiculous but it's raining on my newborn experience
