Baby won’t eat when not home

My daughter is 4 months as of yesterday and recently she won’t eat in the cradle position, or any position that requires me holding her, which is the position I use to feed her when we’re out.

She will only eating when laying down on a bed.

So when we’re out she freaks out looking for my boob but when I try to give it to her and put it in her mouth she freaks out even more!

Idk what to do! I can’t go anywhere for more than an hour with her.

She also still eats every hour and a half - two hours.

It’s driving me crazy!
