it is tough with my older kid too. he is 3.5 years old and we have a 7 month old baby. our helper came just 2 months before the baby came. at first he was alright with her. played alot and co operated. after the baby came, all hell broke loose. he refused to listen to her. meal and bath times became complete brat behavior training ground. i took over the situation, ate with him, bathed him, played and took care of him as much as i could. his behaviour changed. at times when i couldnt eat with him or bathed him, he accepted that auntie will do it. thing is, it's not my helper's fault. nor is it the baby's. he needed reassurance that she was not my replacement.
when we first had our helper, her main chores were cleaning, cooking, marketing and playing with my son. i wrote down what we did in a day by the hr. so she had an idea what the key things to get ready, like lunch by noon. she did not take over basic care like bathing or feeding for my son, because we both agreed that it may be too sudden for him to accept. so they bonded through play times. i gave her a list of things she can do with him while i napped. i also let her sit with us, be involved and observe how we play. things like art and craft, reading, playing with puppets etc. are great for conversations, jokes and exchanges. (more than "ok" response i think) gradually, she helped with his basic cares after observing us.
