Am I overreacting?

Please tell me if I’m overreacting. My father-in-law and his wife have me really angry because I feel they completely brushed off our second child’s birthday whereas they went all out for our first child’s birthday. For our oldest. my father-in-law took the day off work and literally made his wife quit her job and find a new one because her boss was being a jerk and wouldn’t let her have the day off. He also gave us a budget of $150 for a gift to send him that he could buy for her. For our second, they immediately responded with sorry I work when we invited them to the party. They then 2.5 months after the party/birthday mailed us an lcd drawing pad that’s rated for ages 3+ and was only $10. Never once did they ask what she would like/need. I’m just really upset that it seems like they could careless about our youngest. My husband also isn’t happy with his dad for brushing off our child.
