toddlers separation anxiety over toys?

it sounds like his toys are like his comfort blanket. This is perfectly normal and he will grow out of it. My son is 26 months and we cart around 2 stuffed doggies and a blankey everywhere we go, heaven forbid I forget to grab 1 of them!

totally normal! Sometimes the only way I can get DS1 to eat is if Thomas ( or whoever) "watches" him eat his dinner. likewise , we've established my son's "shed" ( a low shelf) in his room , where he puts these toys to bed at night. Works great for Thomas etc. too - thomas doesn't sleep in a bed- he sleeps in his shed. It's even better if your little guy can still see thomas from where he sleeps. My son is now 3 years old and we have a rotating number of things that end up in that "Shed" depending on what he is having trouble parting with that night. Totally normal, and eventually they start to grow out of it , OR at least change to new/different toys :)

It sounds like they are his lovey. they give him some kind of comfort and he obviously needs them, like my kids need their loveys...which are blankets.

Try finding a safe place for the trains. get a box or container that can be their "home". This way (it may take time) but if he puts them in "the box" when he cant have them he will know they are safe and will be there.

If you feel the trains are his lovey, google. They are really important to a child that has one. They become apart of them, make them feel safe, a best friend. My kids loveys are like majic. When they are sad, hurt or tired when theyget their lovey....everything seems to be all better.

it's no big deal to allow him a small toy at all times.
