Hi my little girl is 8 weeks old and has suddenly decided she hates her carrycot she will not go in it for longer than 10 mins and would prefer to be in the sling ( baby bjorn) however she’s getting heavier and I’d like her to use the pram more. We have the sliver cross reef, any tips please? Our walk today was horrendous! She cried and screamed the minute I’d try and play her in the pram, I’m guessing she is too young to use the pushchair section yet.
