Having just been laughed at and called daft by my Mum, I'm going to take the risk of the same happening here...
We're moving from a house where bedrooms are within shouting distance of the sitting room, to a more 'traditional' layout where they are upstairs. DD (aged 5) is suffering a bit from anxiety and hates being alone (we're working on it).
She's got into the habit of yelling for us wherever she is in our (small) house. It's driving me nuts, and in the new house for us to hear her she'll have to yell pretty loud. With accompanying risk of waking her baby sister who will have the room next to her.
I thought it might be an idea to give her a walkie talkie at night time. That was she can call for us if she needs us, she'll know she's not "alone" when she's trying to get to sleep, and there's a chance she won't yell and wake up DD2.
DH's alternative was to get another monitor, but the idea of getting a monitor for a 5 year old...
AIBtotallyU to consider this?
