I have a travel swing - I love it because I can move it around the house with me, take it to grandma's, and it doesn't take up much space in my tiny house. But the downside is that it doesn't have a lot of power, and it's starting to struggle to swing my 12.5 lb baby. Another month and I'm afraid it won't be able to swing her at all anymore.
If your baby liked the swing, how old were they when they stopped using it? I really have no idea what's normal. If most babies use it for a long time I might try to snag a bigger one secondhand...
Re: STMs: at what age did you stop using the swing?
I used mine until she didn't like it anymore...a long time!
