i think they are pretty clueless when it comes to clothes and babies as in the nursery tour they were saying about having only 7 white sleepsuits or something, like thats enough when all babies do is eat and shit, and vomit, like imagine is amber was a refluxy baby and vomited all the time, 7 sleepsuits isn't enough! then the sizing issue, everything she wears absolutely swallows her, you can get snowsuits in prem, newborn, 0-3 and so on, they just didn't have a clue!
edit- How much help do you think they got from their families, as her parents are GPS they would understand the severity of cot death and they leave amber in that huge blanket! theyve also had 4 kids so they would know about sizing and clothes but they just didnt seem to have a clue! maybe they asked before hand for no un solicited advise or simply just didnt listen
