Potty training advice welcome!

Amanda

My son is 19 months right now, shows some signs of potty training, like announcing when he’s going but that’s about it. He does come into the bathroom with us but has never gone in the toilet. Second baby is due March 3rd. Should we start some potty training now or wait maybe until his second birthday in June when things are (hopefully) more settled with the new baby?

Thank you in advance.
