I’ve never breastfed (physically couldn’t) so don’t know the routine. But I gave my son vitamins when he switched from formula to cows milk. Every night I set everything up for the next morning. So bottle, vitamins, cereal bowl, cereal, etc. That way I don’t forget.
Mine never got vitamin d drops. Both of them were exclusively breastfed and born in November when there is little sun. They are both 100% healthy. Get him out in the sun and he won’t need the drops anyways.
Definitely not the only one! I forgot so many times with my first even though they were right next to me too… he’s 3 now and has lived to tell the tale so it’s not the end of the world 😂
