Are you wanting to have a 3rd? If so, how close in age to your second?

I have 2 girls who are 23 months apart. My second is currently 4 months old. I know I want a third baby but can’t decide when to do it. I love that my daughters are 2 years apart but to be honest I sometimes think we should’ve had them either closer or further apart. My eldest has only just come around to interacting with the baby and putting her jealousy behind and I feel like 2 is a tough age for them to accept a new sibling.

Can anyone share their experiences or thoughts? We are thinking about TTC at Christmas which would mean my LO would be 18 months or so when new baby arrives.
