Please humour me as I try and predict the future. Myself and DH come from fractured families and I’m not sure if there’s patterns to sibling relationships or not.
We have DC aged 4 and 2. When DC2 was born DC1 was instantly in love. There’s never been any obvious jealousy and they do seem to adore each other. If I kiss DC1 goodnight they prompt me to go and give DC2 a kiss goodnight. If we drop DC1 off somewhere, DC2 cries until DC1 returns. They do bicker but they do genuinely seem to enjoy each other’s company. They prefer sleeping in the same room and like to do things together and seem to quite equally gain confidence from each other.
Does this bode well for a positive future relationship or is it all irrelevant? My DH wasn’t keen on his brother from the beginning and they never really played together. They’re now quite estranged. A good friend said when her younger brother was born she was very jealous and again, they don’t have a good relationship as adults.
