When she returned home in series 1 and series 3, her children, apart from Carl, treated her with nothing but suspicion and hostility for leaving them with Frank. Fiona (in series 1) and Debbie (in series 4–6) were especially hostile since they were the ones who were forced to take on the household duties. Even when Monica returned for an extended stay, Debbie was still the one to look after Liam and to an extent, her older brothers. Although Monica wanted to be a good mother, and was shown doing some household chores, laziness and selfishness prevented her from being any real help.
