this morning my DD2 fell forwards out of her car seat and smashed her head on the fireplace. I feel terrible that I didn't strap her in. She has a huge bump and bruise on her forehead and I am worried about her. I think shes' ok. She's eaten and had a nap and played an giggled and smiled and acted normally since the accident(once I stopped her screaming) but I'm soooooooo paranoid that she's not ok. Any advice tips on what I could do, refresh my memory on what to be on the lookout for please. Feeling a bit wobbly
