Can I add a different perspective, if you don’t mind?
When I read your OP I heard a whole lot of guilt about letting your daughter down if you went ahead. I also heard that you’d like another DC in the future.
My situation is almost opposite to yours. We ended up with over 4 years gap between DC.
And I still had guilt.
Guilt that as I dragged by youngest two and fro on school pick ups that she was getting ignored (spoiler alert: she wasn’t, she was adored by my eldest’s peers and gained experiences and community from them). Guilt that my just starting school boy was exhausted from his little sister waking him up (spoiler alert: i realised years later he sleeps like a log and was probably just tired from starting school).
I will always remember him standing at the other end of the room when i told him, I couldn’t play that moment as I needed to feed his sister, and in this little voice he whispered “but what about me?”.
Will it be hard with two little ones? Probably.
Will it be easier if your husband helps more? Probably.
Should you make a decision based on guilt about something that hasn’t happened? Definitely not.
No matter the age gap, there will be compromises.
No matter the age gap, there will be mum guilt.
But guilt is not a good reason to make a decision.
You’re doing your best. You will do your best.
The compromises, the balancing, the juggling won’t stop when they start to walk, start to talk, go to school. That’s part of being a family.
We’re still having to say no to one of our children because that’s often the cost of saying yes to another. We have limited resources whether that’s attention, time, money. And opportunities that might come to one child aren’t always offered to another for reasons outside of your control.
For every downside there’s an upside. Whether it’s learning to give and take, or the friendships that develop between silblings. And I consider myself lucky that (as of today!) my DC adore each other. They look out for each other at school, hang out with each other and love each other deeply. And from watching friends with the full spectrum of age gaps, that’s definitely not determined by the number of years between their births.
Speaking as someone whose eldest is less than a year away from leaving home, the decisions you agonise over, the compromises you make but worry about, your children rarely remember.
No matter their age difference you WILL feel guilty over the compromises you make. Please don’t let that be the reason for your decision.
