Feeding
When Lyla was first born she was a strong feeder. It was Jay who had a weak suckle and would take forever to feed. Lyla is also so much easier to feed solids to.
Rolling Over
Lyla was the first to roll over the day after she turned 2 months old. She first rolled from her belly to her back. Then one week later she rolled from her back to her belly and was that way when I awoke her from sleeping.
It took Jay until he was 6 months old to accomplish rolling over. At 6 months they are both rolling 4 to 5 times accross the floor and are scooting everywhere. They both have such good head control when they are on their bellies they can extend their heads high up in the air.
Smiling and Laughing
Jay was the first to really start smiling at 3 months old. He was also batting at the toys over his bouncer seat.
Lyla did not begin to really smile and laugh or bat at toys until she was 4 months old.
Squealing
Jay started squealing and laughing at 5 months while Lyla started at 6 months.
Sitting
Lyla and Jay both began prop sitting at 5 months. Jay has gone on to master sitting in the bath with my hand behind him in case he falls. Lyla at 6 months is still a little weaker but is able to place her hands on the floor to sit for a few minutes.
At 7.5 months Jay began sitting alone with toys in each hand.
Lyla at 9 months is sitting alone with toys in each hand.
Lyla at 10 months was able to sit from a crawling position.
Crawling
Jay began army crawling at 8 months and Lyla at 9 months crawled backwards.
Lyla began crawling forward at 10 months like a baby seal belly flop. At 13 months Lyla is crawling on all fours.
Babbling-Talking
Jay began babbling at 5 months saying abaddadaba. Lyla started at the beginning of 8 months.
Jay said his first word "MAMA" when I came into the room at 10 months.
Jay now at a year says "Baby, Baba, Dada, and JJ." Lyla at 14 months comes up to me and says "MAMA."
Pulling Up
Lyla started pulling up a couple of days after her 1st birthday on July 23rd. She is currently pulling up on everything...in her crib...on the fireplace...sofa. At about 13 months she started cruising.
Walking
Jay just began walking on July 21st. Just like my 4 year old Carly, he began walking two days before he turned 11 months. Lyla just started walking at 17 months right before the new year 2011.
Clapping Hands
Lyla started clapping her hands at 15 months.
