Kids sleeping bag

My wife and I are getting our two year old out on backpacking trips with us and need a bag for him. We are planning on going with synthetic (based upon reading numerous threads on BPL regarding kids messes) and have narrowed it down to two affordable options, both 20 degree bags. The North Face Tigger (33oz – $80) and the Mountain Hardwear Mountain Goat (35oz – $45).

Does anyone have any thoughts/comments/recommendations on these bags?
