Little Girl First Legos!

The 5 stars is for the Legos. I give these to each family member turning 1 year old. Now that we have no toy stores in our town, I turned to Macy's because I found they had "Toys R Us" inside their store. I found, after a bit of a search, exactly what I wanted. I was disappointed, however, at how disorganized the toy section is. It's well beyond the holidays, and the store should have someone straighten this section. It is in desperate need of attention.

NEVER DELIVERED

On December 13, 2025 I bought 2 Mega Bloks MEGA BLOKS 80-piece Big Building Bag Blocks for Toddlers and never were delivered by the seller. I did understand that due to a high-demand of buyers, it might a delay of a couple of days. Now, I do not know where these toys are.

Favorite toy for my kiddos

These are the best building toys! All three of my kids (4,8,9) love to play with them. There are so many things you can build with them. They play in the tub with them, bring them outside and play all around the house. The quality is top notch and they are extremely durable and easy to clean.

Just the right size for toddlers

My granddaughter loves building blocks. She was so happy when I gave her these. They are the perfect size for her, especially since she is only 2. I did receive this for free in exchange for my honest review

Perfect bloks for tiny hands

First Builders Big Building Bag is great for little hands. The bloks are easy to put together and take apart. The colors hold my childs interest and allows her to build anything she can imagine. I like the the blocks come in an easy storage bag. I can take the bag with me when I need to give her something to hold her interest other than at home while she is playing.
