3rd child timing - am I mad??

[Travellingmotherhood]

Would love some advice particularly of anyone with 3 or small age gaps. I have 2 beautiful daughters aged 3 and 20 months. DH and I have finally after months of indecision decided to have a 3rd baby but now the decision is made I'm ridiculously broody. Everywhere I turn friends and family are either pregnant or TTC and I'm wondering if it's time to join the bandwagon and get started TTC or to wait a while on the basis that our girls are still so young.
I absolutely love the 18 month age gap between 1 and 2, they are two peas in a pod but my god they are a lot of work! I'd love to have a small gap between 2 and 3 but I'm worried it will send me over the edge! I'm a SAHM and absolutely love it but there's something slightly terrifying about the thoughts of having 3! Any thoughts welcome!

I kind of went all out qnd had 3 babies under 1.

My dd was born in January and my twin girls were born same year in December, i also had 2 older children.

It was hard work of course but they are all so close and have amazing bond.
If you are in the thick of it now just get on with it i would say, its harder once you have more tike to then adjust to going back to babies again.

My older 2 have a 3 year age gap and although get on they aren't close, prob more to do with they are diffrent genders i don't no.
