going for 2nd child?

[howiloveanicecupoftea]

I can't decide whether or not to have DC2. I have one healthy child, it's been hard work but they are healthy abc happy etc. We get minimal family help and DP isn't very hands on so it falls to me which is fine but it's hard going and puts me off having a DC2. I can see benefits of them having siblings hit equally of them being an only. Then I can't decide how long to leave it. Both DP and I are undecided whereas at least with DS1 I knew I wanted a baby and that it was a deal breaker if we didn't etc. We both can't decide whether to go for a dc2 or not though. Any advice appreciated!
