Maybe it isn't hard for you as someone who is a professional and obviously does this for a living. However with someone that has no knowledge of foaling or foals, weanlings or whatever it can be overwhelming and time consuming.
Everytime I post something on here asking for advice I get conflicting ways of doing things. I have been told I am wrogn for not having a halter on my foal already, wrong for wanting to get a halter on her, wrong for this and that. Everyone has a different way of doing things and for someone who doesn't know what they are doing yes it is hard work. Even if it isn't hands on with the foal it is researching what you should be doing.
Oh and I see you are a guy and have obviously NOT been pregnant. I am sorry but being pregnant does change your body and the way it works whether you are a horse, human, dog, cat, ect.
