how often is too often to send my boyfriend packages?

so my boyfriend goes to west point and I haven't seen him for 2 months and won't see him for another 3. we've been together 4 months at this point. when I was able to see him I'd just bake him cookies for shits and giggles and I've sent him a couple of things over the past two months (I think the last thing I sent was around 3 weeks ago). our monthly anniversary is coming up again (not like we celebrate every month lmao) and we had a tough week last week so I was thinking about baking him cookies, writing him a little note and sending a Polaroid pic of us because I just got a polaroid printer. am I being too extra?? i don't wanna seem like I'm sending too much, but I just miss him and this is how I show my affection haha
