Teething: side incisor coming in before middle ones??

K • Baby E 3.1.17 💙 Baby B 2.25.20 💙 Baby due Nov '22

My son just turned 7 months old & has his two bottom middle teeth. He's started teething again, & now I have found the tip of one of his side incisors on top (next to the middle pair) poking out. Just curious if anyone had experienced this, as I believe it's more typical for the middle ones to come in first... & I'm wondering if the whole front four on top are going to come in at basically the same time! 😰
