1. Miracle Blanket!!!! Changed my nights forever. Wish I had gotten it much sooner.
2. Dr. Brown's bottles. Helped with colic almost immediately. We also switched to Enfamil Gentlease which helped immensely.
3. Leachco Safer Bather Infant Bath Pad. Got it from Amazon. Didn't want a honking piece of plastic that we'd only use for a few months. This pad fits snuggly in our kitchen sink and our LO absolutely loves bathtime since we got this. She always looks so comfortable when she's in it. Stores easy and is always dry by the next day's bath.
4. Mobile - made by Tiny Love. LO loves it, comes with lights, plays classical music and always keeps her happily occupied for at least 20 minutes. It also has a remote control so you can restart it without LO seeing you.
5. Pack-n-Play with changing station. Immensely helpful if you have a 2 story home. Ours is made by Carters and has an organizer for diapers and supplies.
And of course a swing and bouncy seat. Swing was a hand-me-down, so I can't recommend the style - they don't make it anymore. Seat is FP Oceans Wonder. LO loves watching the bubbles and fishes. We keep it on the setting where she activates the bubbles/music/fish.
