As you have done many times now....
Just reading on another thread re 4 month 'regression' and wanted to ask a couple of questions without hijacking that thread.
You mention working on getting baby to take a dummy. Any tips on how? I tried with DS from about 5weeks. He's 16weeks now and still won't take it. He'll chew on it if i hold it for him (teething)
Also, having really worked on naps to get better daytime sleep, they have gone to pot this week. Literally 15 minutes yesterday between getting p at 8 and 4.30pm. Although he wasn't upset or grizzly. Today, two lots of maybe 15minutes. And night waking have gone from one at 3.30am followed by cluster feeding (cosleep) to several.
