I have 18 months between my DD's. I knew when DD1 was 6months old that I wanted to start trying for #2. It took us 5 cycles to get a BFP. DD1 is a very easy going girl. Takes everything in her stride. DD2 is now 4 months old and I still have not had any issues of jealousy from DD1. She loves her sister to pieces. She understands when I have DD2 that she has to wait. I just make sure that DD1still gets lots of attention when I can.

As for worrying about loving another child. For me I worried abit at about 20wks pregnant about this. but I soon realised that you don't take any love away from anyone, you just find more love.
