So M is 4.5 months old and seems to be starting to have a tiny bit of separation anxiety... but it's only in very specific situations. I know at day care she does fine when there are floaters in her room even if she doesn't know them. The issues happen when I'm holding her, and then pass her to anyone other than her dad. She does fine for about 30 seconds and then rolls out her bottom lip and wails until I take her back. I know this is totally normal (and it does melt my heart a little)... but I'm wondering if there is a way to sort of nip this in the bud before it gets worse. Any suggestions?
