Have just had dd3 who is now 4wks old. Dds 1 and 2 coming up for 2 and 3.
We have a 9yr old Staffie who is a softie although gets a bit giddy when people visit.
When dd3 arrived the ILs took the dog to stay with them as the high volume of visitors would've meant his excitement factor would've gone through the roof.
When he was here dd2 never actively liked him but was not scared of him either. She
has always been scared of other animals but never our own dog.
Now he's at the ILs she has become scared of him- a fact that I think is not being helped by the ILs who make a big fuss and shut the dog in another room when we're there.
When we visited yesterday I pointed out that I didn't think it was very helpful to keep making a fuss and then MIL let him in a big rush and he barrelled through which made dd2 into a hysterical mess. 
Now the ILs are making me feel awful for wanting the dog back, saying he must have knocked her over/hit her with his tail to make her scared.
She was NOT scared of him when he was here!
My strategy is to limit fuss made/attention paid to her fear and keep socialising him and her till she gets over it.
No option to keep him in another room here as all open plan although he's not allowed upstairs. No option to keep him at the ILs either as they are going away for 3 months.
so advice needed please? wwyd?
