Bit of background, I (29f) met my partner (35m) at the beginning of last year. He has two children from previous relationships. We were just looking for a more casual relationship as he was recently divorced and I’m a widow.
Cut to less than a year later and our son was born. And I am currently pregnant with our second child.
Ive always had a good relationship with my stepchildren, and with his son who is almost a teenager that relationship hasn’t changed. He’s very sweet with our son however my stepdaughter who is now 3 has decided to be mean and quite nasty both towards myself and my son.I understand she’s jealous and now has to share her daddy with a new baby and that the adjustment is hard for her but her behaviour is becoming more of a problem and is affecting my relationship with my partner.
When I collect her from school she cried and hits and kicks me. She is constantly telling me that she loves her mum and dad and her older brother but not me and not the baby. Last week she put her hands over the baby’s mouth when he was cooing to shut him up.
She has kicked my son, takes his toys away and hides them. And whenever my partner is holding or playing with the baby she doesn’t like it and kicks off until my partner leaves the baby.
She has stopped doing as she is told, stopped her toilet training and has gone back to using a nappy, suddenly won’t sit and eat her tea.
She has been good as gold before the baby came but now she’s even taking it out on the cats and rabbits by spraying them with the hosepipe.
My partner just keeps justifying her behaviour saying she’s 3, which I totally understand however he is reluctant to tell her off or let her know that this behaviour is unacceptable, and tells me I’m too harsh when I tell her off.
It’s causing a lot of issues between me and my partner on top of having a new baby with another on the way.
Is it me? Am I just being mean towards her?
Any advice would be greatly appreciated.
