It has always been in mine and DH plans to have 2 children.
We currently have DD (age 4) and we were talking about TTC next year once she is at school.
I am now not sure if i want another child - DD is a happy sociable little girl but she is hard work (like all children). I feel we are already stretched thin with one child and both working full-time. Also, our DD is currently attending a childminder throughout the summer holidays and I cant face having another child just for them to spend their holidays in someone elses house but going part time/term time isnt an option.
I feel like if we stick to just one child we can take holidays when we can to cover for school holidays and give her a really nice life whereas if we have 2 it will be hard work to try and juggle a baby and a 5/6 year old as their needs are so different.
I just dont know what to do - i do want another child but I dont at the same time 
Has anyone else felt the same - what did you decide to do?
