Hi, looking for advice very nervous dog, 5yr old, had her since a pup, she is a cairn terrier mixed spaniel, lots of energy and loves playing but nerves seem to be getting worse as she gets older, absolute nervous wreck at times, jumps out of skin at any noise, worse since having baby (now 9 months) she is getting more clingy and has recently started whimpering in early hours, also have an older lab who she's normally more secure with and sleeps with but she has been banging door trying to get out, try to give her as much attention as possible but she is so clingy, she is curious around baby, but there has been inevitable change in routine since having baby, e.g. time of walks etc varies, I am trying to get a more fixed routine but difficult to juggle, any tips how to calm her down
