My daughters 6 and since I’ve been pregnant she wont stand properly for her hair doing she always did before she loves having her hair done and loves it to be really neat but since I as pregnant she started tipping her head really far back or forward but pretends she doesn’t no shes doing my baby is now 5 months old and she is still doing it? She gets loads of attention she’s never shown been jealous of the baby do you think it is an attention thing? X
