We have a beautiful 3.5 year old DS who has always been highly sensitive and resistant to change. He is hard work in comparison to our friends children, but we've found ways to make things easier for him (and ourselves) like prepping him before we go places, reassuring him etc. Last month I gave birth to our DD and I honestly feel like I have ruined everyone's life. Whilst I was pregnant I suffered with really bad SPD so couldn't play with my son as much or even walk by the end and relyed on my husband to do most of the looking after of our DS. I felt a shift in the relationship between my DS and I and it feels like we're just getting further and further apart. He's jealous of the new baby and tries to nip/ hit/ bite her if she is even put down so we have to hold her all the time when he is around. It's exhausting and I feel so much guilt that I am neglecting my DS and my DD. Please tell me it will get easier, because I really can't cope at the moment.
