B.M.
Around 6 months seperation anxiety can start. My first child was in daycare so we went through this during the day. All the sudden he cried when I dropped him off. I was a SAHM with my second and he started crying just like your little guy at bedtime. With both kids it started at 6 months.
Now I have a 5 month old daughter, and am just wondering when it will start for her.
The boys sereration anxiety after a month or two. I would love to get together. We could do some scraping or stamping. I've recently found the best clear stamps and clear blocks. Also, coordinating papers, inks and embellishments! I'd love to get together!
